Not sure I havent beat the myself but I am past the snow part which so far was really great part of the game when the shit goes down started to go down.
One thing I hate about this game is the transition between game play and cut scenes is horrible. Which I am glad I am not the only one.
Scat imo FPS are probably the most popular genre in video game, at least I think so that why there is so many plus your list has some many old games. I do feel what you are feeling but with fighting games. Maybe it is not the same but fighting games dont interest me any more. I been trying to play MvC3 and just something about doesnt interest me. Maybe it is not the games fault maybe it is just I dont care for fighting game. I mean I love Street FIghter but any other fighting game I trying I never enjoy it. But something about Street Fighter I seem to always love. Maybe it is nostalgia since Street Fighter II was the very first video game I ever owned on my first system which was SNES.
