It's called freerider 2. It's basically the best incarnation of "create your own track then ride on it" I've ever seen. The physics are really cool and there's multiple vehicles you can use.

To get an idea of the type of stuff people are pumping out for this game, check out this youtube video of a recent map contest:



The best part is it's really easy to share levels! It's just copy/paste text. Since it's so big I'll upload a level I made recently while suffering from insomnia.

It's pretty tough, but definitely doable. A cookie to anyone who can complete it. BTW, I recommend the mountain bike for this one.

Also, post your own creations in this thread. I'm interested to see what the demented minds of Massassi come up with!

Haha man that looks neat... not sure I would dedicate that much time to making levels but playing looks fun.

I'm not creative enough for games like this.

damn you free, give me my 2hrs back
