The purpose of a game is to have fun. If you're not having fun, then the game has failed. A lot of these FPS games are just made to create a money tree for some of these developers and publishers. Many of these FPS games are hollow and lack any sort of depth. No one tries to innovate. Everyone is trying to be a realistic military shooter. It's sad, really.
I don't often agree with that one, but... if the purpose of gaming isn't to have fun, then what is it suppose to provide?
just for reference. Journey is one of my alltime favorites, nevertheless, is not fun at all. Spec ops the line is way 2 depressing (the opposite of fun), yet i love the game. Silent hill, Shadow of the colossus, nier, blablaba, etc etc i guess you have the idea.
