I thought our Brawl scuffles were worth it, you heartless monster.
Anyhow, the games that I've enjoyed most have been your aforementioned Mario variety; Brawl (where I use the Gamecube controller), Kart (where I never use the wheel) and Galaxy (where other than a bit of shaking and pointing the Wiimote use is minimal). So yeah, there hasn't been a whole lot of original stuff to work with. I'm enjoying the games, but I'm not really doing a great deal of new stuff with them.
Star Fox could be a chance to use the Wiimote cleverly (if they'd just let someone make it who didn't suck!!), and possibly Pikmin as well... The 'Wii ____' series of games have been pretty good, though.
