Because people don't buy the games they make.
Examples:
- Red Steel (1 did okay but 2 flopped)
- Goldeneye (1.03 million which is good, but lets be honest it would probably be at like 3 million already on 360)
- Black Ops (only 0.79m compared to like 10 million already on 360)
- Metroid Other M - I know this is made by Nintendo but its more a western audience targeted type game and it's flopped so far with just 0.78m sales.
And also because non-mainstream games don't sell well in general on the Wii. The top 10 selling Wii games all have something to do with Mario or are the Wii series (sports, fit, etc.). The best selling game not in these 2 categories is a cheap party game (Just Dance 2). Where's the motivation to make an expensive high quality game when if you make a cheap game called "Wii fun party time" its an automatic million seller.
