onyxmeth: braid is coming out for pc this month, but i guess you might mean console exclusive.

Nope I mean full on exclusive, which is more than I can say for your pick of Rez, which is on it's third console already.

PS3: Metal Gear Solid 4/ Killzone 2
Xbox 360: Gears of War 2/ Halo 3 (or Mass Effect)
Wii: Super Mario Galaxy/ Legend of Zelda: Twilight Princess

mass effect is a ps3 exclusive i didnt know that lol

u should probably fix that

Well rez HD did get some improvements against the dc/ps2 versions (sound, graphics, rumble support), which is more than you can say for braid, being pretty much identical on pc/x360. Braid is definately not exclusive, nor has it ever been, but lots of people are listing console exclusive games so I guess that works.

well i changed mine from viva pinata to tip because the first was on the pc

Braid has been exclusive. It's been exclusive since August 6th 2008. What other console/handheld/PC were you able to buy your copy on that I am unaware of because from everyone I've ever spoken to that has played this game, they have all played and bought it on an Xbox 360.
