OMG, you have to make the on-line version!
hey man, I love the game. I only played with the WRX and the Charger but i had a blast. I played for hours. I do however have a few sugestions for the later version (I pray there will be 1)
-more options (especialy parts and decals)
-some options in the show room
-and just more interactivity in general
I'm sure you've heard all this before but you said you wanted feedback, so, there it is! I look forward to your future work (especialy the on-line game you spoke of). 10 out f 10! W00T!!!
