I tried the Mat Hoffman's Pro BMX demo included in Tony Hawk's Pro Skater 2 and it was really funny because the collision was really bad and I was able to get my character (and camera) to partially go through the wall by trying to go through a specific corner on the demo level.

So of course I burned a CD-R of the game and I'm really hoping it's even funnier when you add in me being able to make my own parks.
