The Arena!

This game is something else… http://www.youtube.com/watch?v=0aPOiW9sCAs&feature=youtu.be

how do people keep others from screwing up their arenas? Its too easy for people to come by and throw up walls and pillars.

I think its way way way out of where people would actually go…

Throw pillars everywhere or put up your own walls to increase the movement aspect.
