Don't have any real fav.
If the game's good I don't really care about the genre.
I hate racing games, but good ol' Stunts (or 4D Sports Racing, afaik) was the hell a lot of fun, for instance ^^
Oh, and I can't stand puzzle games, but Head Over Heels kinda got me, don't know why, though
If I need to relax a bit, that means, If I need to stop thinking for a while, I play mostly easy action games. If I want in-depth story I play RPGs like Ultima or some point n' click adventure via Walkthrough (yes, I play most Adventures with Walkthrough, cause I am rather interested in the story, than just stuck for 3 days in the same room cause I can't find this damn pixel resembling a key)
Uhm, well, anyway, you all know what I want to say, I guess
You should've added an option like "None of them at all" or something like that.
