The Wii demographic practically guarantees (at least at the moment) that mature titles will not perform in line with more family fare.
I'm sure the Wii can support mature titles, as RE shows, but people need to be realistic about their sales potential.
I have a Wii and so does most everyone I know. And in all those cases it is the family console and there is no chance of mature games being purchased.
This gen unlike last there are two viable platforms for mature games and one in particular (360) whose demographic is perfect for mature titles. The Wii has the market-share but I really doubt that within that market-share it has (so far) as many potential mature game purchasers as the PS2 did.
The actual install base for mature Wii games I'm convinced is way lower than its total install base, and probably way lower than for the PS3/360.
Try to be reasonable... its easier than you think...
