Halo and Final Fantasy. I don't own a Xbox, I can't find the ones on PC. For FInal Fantasy, I have a couple of them, but I never have the time, there's always other games.

Most of them, never played GTA, Metal Gear, Halo, Call of Duty (or any fps) , Assassins Creed, Uncharted, God of War, etc. I've no interest in trying them either.
From Nintendo I still have to try Smash, I'll fix that in this gen.

uncharted, forza, kid icarus, final fantasy, battlefield, kingdom hearts, LBP, mother,fire emblem, far cry, animal crossing, dragon dogma, street fighter, DMC(i prefer bayonetta), silent hill, Banjo Kazooi, conker, kill zone,diablo, civilization, spyro, Mario party and golden sun

Pokemon

Off the top of my head: Kirby, Pikmin, Uncharted, Gears of War, God of War, Kingdom Hearts, Little Big Planet and a lot more which I haven't played (yet).

(One might add pretty much all of the Xbox franchises.)

The only thing that comes to my mind is Pokemon.

LBP is realistic?  GoW is pretty fantastical too.  I would recommend Puppeteer for someone who likes off the wall stuff

Tomb Raider (Not the Reboot)
FIre Emblem
Kingdom Hearts
Dragon Age
Assassins Creed
Diablo
Everquest
Dark Souls
Metroid
Infamous
Fable
Gears of War

For me

Final Fantasy: Ok I played a GBA one awhile back and got bored in a couple days but never touched the main series. The length has always been an issue and I wonder if I can adjust to turn based combat.

Unreal: Just never had a chance and now it's a thing of the past that I've never been tempted to go back to

Fire Emblem: see final fantasy

Animal Crossing: always seemed terribly pointless. I'm not into endless games with no real goal like any Simulation which Animal Crossing seems like a cutesy version of

Any big strategy game other than Rome Total War and Age of Empires 2.

Grand Theft Auto. I have GTA5 though but I never have gotten to playing it
