it would be cool but there are a few problems
1: is shredsauce even copyrighted if not then ea would not have to buy it
2: i dont want to pay more than $30 for shredsauce
3: there is not a big enough market for the game
4: would they make it for computors too cause i wanna be able to play at school
5: how often could they update it
6: i dont have an x box or a ps3 but could you leave go to ns or any other site with levels, coppy the code and then go back and paste in the load section
