MW2 for both 09 and LTD.

End of 09 -- MW2

Lifetime -- NSMB Wii

NSMB Wii will have legs, MW2 won't have legs

simple as that

End of 09: Modern Warfare 2, without a doubt. Nearly 2.5 million preorders in North America alone, and with 2 weeks to go until release. It won't sell under 4.5 million first week on PS3 and 360 combined. And sales will continue through the holidays. Not even a Mario game stands a chance against that. NSMB DS just broke a million first week.

Lifetime: This one is harder, because while CoD4 has the best legs of any PS360 game, the legs still pale in comparison to some Wii games. NSMB DS sold some 20 million, the Wii version obviously won't sell that much. MW2 should manage 13-14 million. A virtual tie, but I'll give it to MW2.

Yeah, cause CoD games never have legs....

WaW has sold 3m this year, CoD 4 has sold about 1.75m this year, and in 2008, CoD 4 sold 5m last year. Quality sells games, and MW 2 is going to be even better than the first

what?! Of course MW2 will ahve legs! They will be giant legs!

nsmb wii is just a 2d port of the ds game isnt it?
just because there is a lack of other games to play does not make this game the second coming.

MW2 by a mile.

and even if it was the second coming, it will not outpace mariokart or even galaxy. games like wiifit and wiisports are what nintendo represents now... not mario.

some say.. but its 2d!, that hasnt happened for years and years= big sales.
but NO. there is a reason a 2d mario game has not been on a home console in years (cough.. paper mario) that is becuase it is a regression.

I will say it again, MW2 by a mile in all respects.

Doesn't CoD 4 currently out sell Mario Galaxy on a weekly basis?

Wow. You really think a lot of MW2 huh? 13 million in less than two months is a holy hell of a lot of copies every week.

1: This game is not a "port."
2: Mario is still one of, if not the singular, most recognizable characters on the planet. Certainly moreso than Miis or Wii itself, i bet.
3: This isn't the 90's anymore. We no longer condemn games because they aren't 3D
4: Change in perspective, in terms of Mario games, is tantamount to a rather large change in gameplay. Even without the competitive/cooperative multiplayer element, 2D Mario is more broadly appealing than 3D mario, due to it's arcadey nature. 3D Mario is simply less accessible.

MW2... sadly...
