OH MY GOD. How many times must we go over this... Third party games don't sell on Wii because 99% of them DON'T DESERVE to sell on Wii! Seriously, name me ONE great quality game on Wii, developed by a top tier third party, with great potential and appeal, that DID NOT sell well on Wii and should have. And don't you dare say Mad World, No More Heroes, or Zack and Wiki. Those are NICHE titles that anyone with half a brain knows would not sell on ANY console. Monster Hunter 3 should prove as a great example of a game with actual EFFORT put into it that became worthy of its good sales.
The argument that all Wii owners are somehow conspiring against 3rd parties really needs to be dropped, because it's downright foolish. Make good games that appeal to people, and they will sell. END OF STORY. This is true for any console.
You have some nerve to blame the Wii owners for not buying what is largely an extremely shoddy and half assed effort from 3rd party games for Wii. Wii gamers are not strange creatures from mars. They are simply GAMERS who want GOOD games. Most third party games on Wii simply don't provide this. Maybe you should stop pointing the finger at the consumers, and blame, oh I don't know.. the people actually MAKING the game!
