BC4000 - Civilization Model

Last modified

Description of App

The BC4000 APP is a turn-based strategy game. The game has an online mode, a hot seat mode and a single player mode. You take on the role of the ruler of a civilization, attempt to build an empire in competition with other civilizations. The game begins in 4000 BC, before the Bronze Age, and can last through to AD 2100 with Space Age.

Along with the larger tasks of exploration, warfare and diplomacy, you have to make decisions about where to build new cities, which improvements or units to build in each city, when to expand your empire by new settlers, and how to transform the land surrounding the cities for maximum benefit. From time to time your cities may be harassed by units from other nations or barbarians. You should protect borders and maintain zones of control.

You can gain a large advantage if your civilization is the first to learn a particular technology and put it to use in a military or other context. Since only one technology may be researched at any given time, the order in which technologies are chosen makes a considerable difference in the outcome of the game and generally reflects your preferred style of gameplay. Please carefully consider about forms of government, tax rates and research priorities.

You can also build Wonders of the World after obtaining the prerequisite knowledge. These wonders are important achievements of society, science, culture and defense, ranging from the Pyramids and the Great Wall in the Ancient age, to Copernicus' Observatory and Magellan's Expedition in the middle period, up to the Apollo program in the modern era. Each wonder can only be built once in the world, and requires a lot of resources to build, far more than most other city buildings or units. Wonders provide unique benefits to the controlling civilization. For example, Magellan's Expedition increases the movement rate of naval units.

The game can be won by conquering all other civilizations or by winning the space race by reaching the star system of Alpha Centauri.

The strategy logic and user interactive concept are inspired by the original Sid Meier's Civilization. Most graphics, music, map and text materials come from public domain licensed by Creative Commons License or General Public License.

At least not in civilisation mode or under siv2 siv3/classic. When you have mapped the entire world, only cities of interests will be shown, regardless of distance. Not sure of augmented though.

I am 100% sure that sometimes units do appear on the list when revealed on the map. However I am equally sure that some other times they don’t. Trying to figure out the conditions.
I think that when a unit specifically reveals another unit on the map it does appear. When a unit was already visible and outside the radius of a city it doesn’t. I’m not sure though.

Submitted by DMNagel on Wednesday, April 13, 2022

You are right about units picking up other units. The units of interest menu is no longer subject to cities alone. If one of your units can see another enemy unit, The units of interest menu will appear. It will remain there for as long as The enemy unit remain in your unit's sight.

In the latest beta version, we will now be allowed to view all infrastructure without having to visit the mini map in the cities menu. From within a city's menu, there will also be a previous and next button that will allow you to jump between cities, along with a button that will allow your governor to automatically assign citizens according to your preferences. Furthermore, you can watch an advertisement in order to become a super player for one turn by selecting the world menu and view mode. When doing this, all units and cities will instantly become available on the map for one turn. Note however, that only the five closest units will be shown in the units of interest menu. The rest will have to be found by locating them on the map. As far as battlefield goes, I have yet to check things out.

There is a new earth map which can be played with augmented ruleset.
Fortresses and airbases can also be added in the editor.

Once the super player view mode has been activated, double tapping on any enemy city will be equivalent to sending a spy into it. You will be able to view the cities production, improvements, population as well as its Minimap. In short, it will be similar to viewing your own cities. It's like spying on a city without using an actual spy. Furthermore, you can go into the world menu and under diplomacy, you can choose to get an intelligence report, even if you haven't made contact with the nation. The only thing that separates this mode from the actual spy, is the fact that the spy can-do sabotage. The super player mode is for viewing only.

Now this is not exactly a big deal, but it can often be a little confusing at times. Sometimes when I open the app, it will be in landscape mode with the charge port to the right for the most part. However, I've realised that sometimes when I open the app, the charge port will be to the left. Does anyone experience the same thing?

Submitted by Panais on Tuesday, April 26, 2022

There is no such issue for me. However after some update the charge port can be on the left of the screen, which was not the case in the past. Maybe the game detects how your device is tilted before you open the game, and the landscape mode is orientated accordingly.

I could no longer stay away from this game.
I have decided to give it another shot and, hopefully, this time I will understand it.
If I need help, I will be requesting your assistance.
We'll see how it goes.
It sounds like an awesome game.

Submitted by DrummerGuy on Wednesday, April 27, 2022

OK. So… I have built my first city but when trying to build something else such as an aqueduct, it does not show me where it is being built.
The other thing is that when I sent settlers to another tile to work on her road or mine, it shows that they are building it but, if I decide to send them somewhere else, the tile where they were before does not show anything. Where is my road? Where is my mine?
Will it be built in turns?
If that is the case, perhaps I should let the settlers there until whatever project is finished. Right?
Please help. I think I'm missing something here. I have had to start over many times because my settlers go missing and explorers get killed. What's going on?
This game sounds extremely fun and I don't want to quit just because I don't understand it.
This sounds fun and I wanna have fun.
Thank you in advance for your help.

Things will be built over the cause of a few turns. You will be notified between turns when it is completed. When you build one city, the responsible settler for building the city is automatically lost. When a worker or settler is building roads, mines or irrigation, they will fall silent for as long as they are working on it. When they are done, they will become available for new orders, which is an indicator that they are done. By this point, the newly built infrastructure should show. Explorers die when they accidentally enter a hut with barbarians, or get killed by an enemy. Note that you can turn barbarians off at the start menu. I hope this was helpful.

There is a city button. Double tap on it to view your cities. Double tap on the city you want to manage. All the info such as improvements can be viewed there. Double tap the change button to see the available improvement options and to select one to build.

Submitted by DMNagel on Wednesday, April 27, 2022

Note that not all types of terrane can get mines. I believe only mountains, glaciers, deserts and hills can get actual mines. You can still mine on other terrane types, but it will merely change the terrane type. Mining a grassland will change it into a forrest and vice versa. Irrigating can also change certain terrane types. A forrest will become a plane if you irrigate it. The ultimate goal is to strike some balance between food, shield and trade for max production.

Submitted by DrummerGuy on Thursday, April 28, 2022

Thank you for the help, DMNagel.
So, once I send a settler to a certain tile I should not move him away from it until he finishes building the road or mine, right?
And, in that case, can I get new settlers to go to other tiles?
Thank you for your help.

Submitted by DMNagel on Thursday, April 28, 2022

When someone is working, mining or irrigating a tile, leave them there until they start asking for new orders again, otherwise they won't be able to complete whatever they are doing. As for getting new settlers, you can most definitely get them by building them just like you would any other city improvement. The only catch is that they cost two population, so you will need at least a population of three in order to build a settler.

Submitted by Panais on Thursday, April 28, 2022

When you finish building a building, the building doesn’t appear on the map. There is a button labeled improvements when you open the city interface, in order for you to know what buildings are currently built in the city.
Regarding tile improvements like irrigation, mines, roads etc., it’s better to use workers to build them because settlers are very very slow at it. Like DM said, once a unit is done improving the tile, it will be available again to order around. Also any improvement will be spoken by VO when tapping on the tile, both on the city mini map and the general map. You can also double tap on a tile of the map in order to view the improvements.
The best thing to do in order to learn the game in the beginning, is to create a game without enemies and without barbarians so you aren’t harassed by the computer and thus learn in peace.
The encyclopedia also has lots of useful information.

Submitted by DrummerGuy on Thursday, April 28, 2022

I just saw that the settler just finished building a road.
I will look for a good place to build a mine or something.
Thank you for your help.

Submitted by DMNagel on Thursday, April 28, 2022

Note that you can also put settlers and workers on auto work by double tapping on the more button among the orders, should you wish to do so. This will make them automatically move around your city and build whatever is necessary, allowing you to focus on other things such as city improvements or units. Glad to see that you are starting to get the hang of it. Soon you will be building your very own world, but we will get to that as soon as you are ready.

Submitted by Panais on Thursday, April 28, 2022

I think this button is gone with the new update and is replaced by the work button.

Submitted by DMNagel on Thursday, April 28, 2022

Although I'm not sure if the latest public update is available yet. In any case, if not, then double tap on the more button. Otherwise, all buttons including the work button will be part of one single menu in the latest update.

I ended a turn and I got a message saying that my tribe ran out of hit points because it was not supported by the city.
What does that mean?
How do I prevent this from happening again?
Thank you for your help.

Submitted by Panais on Thursday, April 28, 2022

That means that you are playing the augmented ruleset which you shouldn’t do at the moment under any circumstances. It’s much more complicated than the normal ruleset and it will give you a very hard time.
Start a new game and make sure you are using the civ2 civ3 ruleset

Submitted by DrummerGuy on Thursday, April 28, 2022

I will start a new game as you advise.
Thank you very much for your help.

Submitted by DrummerGuy on Thursday, April 28, 2022

What can I do when the turn is ended and it says:
Citizens have stopped working on (46, 32).
does that mean that the unit has been lost?

Submitted by DMNagel on Thursday, April 28, 2022

When you go into a city's interface and accidentally double tap on a tile in the mini map, you will stop the citizen from working there. To fix this, you must either double tap on that tile again, or use the max food button to automatically arrange citizens for max food production.

Submitted by DrummerGuy on Friday, April 29, 2022

Knowing that this can be fixed so easily is definitely a relief.
Thank you for helping me.

Would you say that it would be better to disband some explorers or should I turn them into something else. Maybe they can be turned into settlers. Can they? I think I got too carried away but my city started creating warriors from the beginning. I didn't notice that until it was too late. Now I have two cities and the other one apparently has an archer.

Submitted by DMNagel on Friday, April 29, 2022

It's okay to have as many explorers as you want. However, archers and warriors, along with other military units is better left at home, which is to say in their respective cities. Having too many military units exploring the fields will cause citizen unhappiness which can later turn into city disorder. In theory, The more explorers you have, the faster you will unlock the entire map, not to mention finding hidden huts with scrolls, treasure, units or friendly cities. However, given the citizen unrest, it becomes a trade off. Some units can be upgraded later in the game, as long as they are standing within their own cities. I hope this was helpful and you're welcome.

Submitted by DMNagel on Friday, April 29, 2022

You can either disband some of your units, or send them into cities and have them stand sentry. If you let a unit stand sentry, it will stop bothering you with orders every turn and wait for you to activate it from the nation control menu when you feel like using it again. However, in the event that someone is trespassing close to your sleeping unit, it will wake up again, indicating trouble.

The developer just added online support via game Center. Now you can play online against other players.
