Seeking action types games for the Mac

I have recently become interested in gaming on my Mac. I haven’t found that many games, maybe there aren’t that many, I don’t know, but I thought I’d ask to see if there were any more that I don’t already have. I have shooter, and another similar type game that I can’t think of the name of right now. I deleted that game though, because I couldn’t really understand how to do it. Anyway, any suggestions you could give would be most appreciated. Thank you
