Why did you guys buy a Wii, if you don't like the games available for it?
Also, no matter how much you wave your arms, developers and publishers are not going to flush their money, and years of the lives, down the drain so that 5 Wii owners can buy something cool. It has to have a decent chance of success. Games like Monster Hunter are guaranteed smashes in Japan -- wait'll you see how it does in the West.
Anything established and Japanese will do well on the Japanese Wii base. Otherwise, its party games and fitness games, to put bread on the table of game devs. Game development is not lucrative at all, unless you're very, very lucky. Most game devs work for average-at-best wages (for their skill sets), and never see a dime of royalties. When I say most, I'm talking like 95%.
If you don't like Wii games... get another console. The Wii is fine as-is, for the consumers who bought it for what it is, and not what they wish it would be.
