OK, I downloaded and played both Victory Run, and Big Run (arcade). Big Run does copy some things, and it doesn't play as good, but the graphics are amazing! (I'm a sucker for scaler games.) The drum samples in Big Run sound like Phil Colins called me up over the telephone, and instead of him playing his drums, he farted into a sock.
Also the crashes are better in Big Run, but at the end of the day, Victory Run is better.
