I don't know where this is coming from, but perhaps the same reason other people hate nintendo: Selling out. why make GOOD games when you can make shitty cash-in games that sell better than anything else (Wii Sports, Wii Play, Wii fit, etc)
I'm not bashing nintendo, some of my favorite games this gen are Wii games and when nintendo's game is on, it's ON. Donkey Kong Country Returns, New Super Mario Brothers Wii, Smash Brothers Brawl, the Mario Galaxy games, Twilight Princess, the Virtual Console...all awesome, but for every Metroid Prime game, you have Just Dance and Carnival Games.
And Just Dance has sold millions of copies.
That is why I dislike the Wii. When it's good, it's phenomenal (and it has more than its fair share of good), but when it's bad (and it is frequently), it's an insult to gamers worldwide.
