Wow, it is a sad day when I see people trumpeting Treyarch. CoD3 was a flaming piece of crap and World at War was, at best, a decent game. Other than that, they made Quantum of Solace for the Wii . . . let that sink in. 2 HORRIBLE FPS Wii games, and one OK one. Treyarch's track record is incredibly spotty, not just for the Wii.
Wii fanboys can be such babies when they hear a developer knock their sacred cow. The Wii is not a processing powerhouse and is limited. IW updated it's engine for MW2 to make the game what they wanted to offer. If they designed it to deliver the same experience for the Wii as on other consoles, it just wouldn't be the same game. Sorry fanboys, as much as you love Nintendo and the Wii, there are somethings it isn't cut out for.
IW didn't want to put out a crappy CoD game on the Wii, they let Treyarch do that (and why Treyarch makes CoD games at all is way beyond me). The Wii is not the gritty FPS console, sorry if this is news to you, but seriously, come off it. Attacking a developer that makes good games just because they don't have their world revolve around Nintendo like you expect is just silly.
I give this thread a 9.2.
