I have been working on a Mario Kart/Crash Team Racing style game for the past couple of months(for the XBOX and PC using XNA) and so far I'm fairly pleased with the progress. My game desperately needs some decent artwork though and I lack the time and skill to do it all if I plan to have my game ready for testing this summer. The game will have a barnyard animal theme and cartoonish 'Wile E. Coyote' style attacks and power-ups. Any Modellers or texture artists interested should visit my site
