Hmph... I played a few rounds of ETruck at a friend's place over the weekend (lucky journalists!), and I thought it was GREAT FUN. Everyone there really enjoyed the experience, and sure, part of it was that it was early and exclusive, but I just really had a lot of fun steering with that remote.
It's different, and I don't mind that. Of course, I am a sucker for games featuring boost and large jumps, so I was biased in that regard. But personally, I think that kiosks featuring ExciteTruck will sell a lot of Wiis.
Also played Wii Sports Tennis, Bowling, and Boxing, and thought they were all a good time, as well, by the way. Party games for the next generation, for sure.
