Realistic racing games, most RPGs, most sport games, most fighting games (the exceptions I'm mostly talking about are Nintendo takes on each genre)

Mario.

HALO 1-3 and odst

all COD games but mostly MW2

bioshock 2. it was cool playing as big daddy but the hole game feltout of place and didn't fill like bioshock.

Mario(including kart), mgs, zelda, fable and metroid.

I feel I should address these two.

Shadow of the Colossus is simply incredible. It is pure gameplay. There's ten minutes of story at the beginning and ten minutes at the end with maybe another fifteen minutes interspersed through 12 hours of gameplay. You owe it to yourself to try it out - it's nothing like Ico.

God of War - I did like the original God of War, and  only enjoyed CoO because I was already such a huge God of War fan. But they are both far and away the worst games in the series. Number 2 and 3 improved upon them in every single way. No more game-winning combos. No more ugly textures. Way more intelligent boss battles.

As for me:

Realistic Racing Sims - I get no enjoyment out of these whatsoever. It is a pain to drive all of those cars. I don't want to think about gear shifting and traction while playing a game.

Street Fighter - Only because I suck at it. All of my friends also suck at it, but that's not the point. It just doubles the suck. Tekken and Soul Calibur are fine because they are easy to pick up.

Ninja Gaiden - DEMON BATS.

I also despise Madden, but only because I've never played or watched American football, so I know nothing about it, and have no idea what the hell is going on.

GTA and Red Dead. I am not a fan of Rockstars open world games at all.

Music games pretty much for me.

To be honest I don't know.

Would probably have to say games like Cooking Mama and World of Goo. Just isn't my thing, and I play so many different genres.
