Before I get started I would like to say that I am not a fanboy of any system, I just like one system the best and expect every game that comes out on it to be the best, and all its competition sucks! :D (well I thought it was funny)
Currently, to me Nintendo isn't doing well with the WII, in fact I think the WII was a waste with the exception of a couple good exclusives; though last gen, and the gen before that I think Nintendo did very well. The Nintendo 64 was probably Nintendo's best console, it was filled with great classic platformers, and other greats like Majora's Mask and Ocarina of Time, so I think that Nintendo did great with that gen. Last gen they released the Gamecube, which -in sales- came in last place in the console wars, but to me the Gamecube was a really good console, and I also think that the Gamecube showed how much Nintendo caters to its fans, I mean with the GameCube Nintendo gave fans games such as StarFox Adventures, Paper Mario: The Thousand Year Door, Super Smash Bros. Melee, and much more, all of which were great games, and all of which were originally showed on the Nintendo 64, which is why I think that they cater well to their fans. And this gen, well, this gen is the one that I think they screwed up, with the WII that is, to me the WII has next to no quality games, but I can still see how they cater to their fans through the WII, but not as much as the GameCube or the N64, to me they could have done much better with the WII than they have, they should have brought more quality games to the WII (I mean they haven't even brought a Zelda game to the WII yet!), and that really would of made the difference to me, because right now I think the WII is mainly a waste of time from Nintendo.
