That is Hard hmmm I don't think I have an overall fav. but I can break it down.
FPS-Call of Duty 4
MMO-World of Warcraft
Adventure-God of War games or Metal Gear Solid games
Little big adventure, You've probably never heard of this one but i absolutely loved it, when i was about 6 years old me and my sister used to play this together . Also it probably has the best video game music I've ever heard. And the story line was also fantastic.
