Against the grain: Why is the Wii so rubbish at mature games?

[LordTheNightKnight]

Good OP, although some will not read it and instead go off the title (learned that the hard way).

I'm adding that there are hit games in that style on the Wii. They just have to be appealing. Umbrella Chronicles was appealing. Darkside Chronicles tried to hard to be a horror experience (and many gamers saw it as trying to throw a bone in place of a real RE game) and thus did not have as much appeal. Extraction was seen as a dumbed down spinoff, and was ultimately a boring rail shooter, and thus had little appeal.
