A fleece arena would be awesome, But TNT WARS?! EPIC. Try to kill other players with TNT. You get obsidian upon entering to build a TNT proof house to spawn in once you're dead. There are chests all over the map that contain TNT. You are allowed to build structures, but watch out for GREIFERS! GREIFING is allowed!
