MAking levels on this game is really fun and takes a while, but you can create just about anything. I got this for Christmas, and i wanted to check out some user created levels before I played and it really suprised me what people could come up with!
My first user level was a Sonic level and it was complete with a flying tails and the checkpoints from the sega games. I was impressed.
I have started making a war-time level with burning buildings and a tank. I cant wait to finish it.
Buy this game if you have online play, as this is whats its for. If you dont have your psp connected. This game is rated 2-3 stars.
