I like the trivia games.
I like Action games and strategies even though I am not into computer games, I am a Play Station lover.
I love playstation too, what are your favourites games?. Did you try Medal of Honor Underground? That's the one I'm playing right now, it's pretty cool although I try to play it when my son is not around because there is too much shooting.
I love RPG's like Final Fantasy and I like mystery games or point and click adventures ;D
I like RPGs like Diablo, and Strategy games Like Warcraft and Starcraft. 3D games are good like Duke Nukum.
Just for the record the "3D" Category should be FPS (First Person Shooter).
I have to go with FPS by quite a bit. My website is a gaming community for FPS games so it's a given Counter-Strike, SOF, Tribes, Unreal Tournament, BF1942
RTS (Real-Time Strategy) would have to be next.... Empire Earth is awesome, Starcraft is a classic, as is Red Alert.
Xtrasweetgirl mentioned PS2...I enjoy that too although I don't get to play much these days. Favorites for the PS2 were Dynasty Warriors 2, Grand Theft Auto III, and Maddan Football...then again, those are the only games I have for it.
