I know it's not a popular opinion, but I really do think certain types of games have traditionally sold better than others on Wii.
It can't be do to quality that Wii series games sell so much better than many of the listed games because quite a few of these games have received higher review scores than any Wii series game.
I don't think it's do to lack of advertising because many of these games have been discussed at great length on internet forums and in the gaming press. Play even dedicated a cover to Muramasa.
Nintendo games aren't immune to it. Galaxy, the Metroid games, Wario Shake It, and Twilight Princess didn't sell like the Wii series games.
I think it has to be do to the fact that much of the Wii's audience is still very much nontraditonal gamers.
