Branduil said:I think games like No More Heroes, SSX, DQ Swords, and FF:CC count as 3rd-party games.
Of course the 360 needs 3rd parties a lot more than the Wii does.
On the flip side, Nintendo's strategy of relying first and foremost on first party didn't quite work out so well on Nintendo 64 or GameCube. Nintendo's lack of compelling third party support is a real eye opener if you just aren't into Nintendo games. I'd say Nintendo needs third parties to the same degree as anyone else, unless they're satisfied with that same niche they've served the past two generations (which they very well may be, since they are profitable).
