I was thinking about all the games I have played on the 360, ps3 and wii, I notice my gaming habit have changed.

Play More of: 

FPS (CoD MW, L4D, Rainbow Six + others)

TPS (Gears of War, Dead Space + others)

Sandbox games (Infamous, Crackdown + others)

Action/Adventure (Batman:AA, UnCharted + others)

Casual Games (Rock Band, Guitar Heroes, Wii Sports + others)

Play the same:

JRPG (Lost Odyssey, Eternal Sonata, Valerie Chronicles, Blue Dragon + others)

Platformer (LPB, Mario Galaxy + others)

Play Less of:

Fighting Games

Sport Games

Racing Games

What Genre do you play more, same and less this gen?

my gaming tastes have not changed and probably never will. I played RPG's then, im playing them even more now and i play less FPS games (MW2 will probably be the last one for me this gen) or just avoid them altogether

My tastes have changed, I've found that I really don't like most current gaming trends which has lead me to the decision to not buy a current gen home console. Instead I've gravitated towards the PSP which seems to hearken back to the previous generations.

no RPG still my favorites.
i think i am done with FPS for a while.

i play less nintendo games, i play more sandbox and FPS games, as well as fighting games.

i play more action games(shooters, sandbox titles etc.), rhythm games and puzzle/casual games.
my love for racing games didn't change so far and same goes to 4X sci-fi games though i never stopped playing them. same goes to fighting games.
i definitely play less strategy games, rpgs, jrpgs, srpgs, platformers, simulations(mostly because i don't have enough time to play those) and stopped playing classic adventure games completely.

also i've got tired of some console game mechanics - i hate random fights in jrpgs or 2d backgrounds with 3d characters. i can't play some older games anymore since they're too archaic to me now.

They haven't changed one bit. Some few games that I used to play more on past generations may have dissapointed me with their most recent iterations, yet in the global panorama it's still pretty much the same:

RPG > Driving sims > Football Sims > Adventure > so on

Also, to me, Retro-gaming > All xD

I've been more into fighting games, but otherwise things have gone unchanged.

wouldn't say my gaming tastes have changed but I am a little tired of playing sequels which change very little.

For example, I'm finding the new ratchet and clank game uninteresting and even boring because it's too similar to its predecessor. I enjoyed Tools of Destruction though.

No, my tastes haven't changed at all.
