THe demo was pretty good. It's a Jet skiing game and you can play 8 people on Xbox livw. It had some interesting water effect. $19.95 retail 2/24 release.
I didn't realize it was on XBL as well. Also played the demo on the OXM game disc and thought it was pretty cool. My wife and I (years ago) rented an N64 along with Wave Race (can still hear that announcer's voice... "Waaaaave Raaace!!!" and had a blast. As a bargain title might be fun just to relive that.
