I think that having the ability to create your own melee arenas, quickdraw arenas, etc. would be an awesome idea. Maybe having the ability to play with freinds on them. I dont know i just think it would be a great idea if that were to come in future updates. I dont think we should have the right to make a complete campaign level only because it takes up to much memory...trust me. So just leave your opinions, comments, and what ever else you could think of.
That is a zero not an o in my gamertag
