Is there any interest from the public to have this plugin for their server? I would also like to do something similar to a Tower Defense type game with a twist on the mobs and upgrades. Minigames are a big thing in Minecraft for a while now, so we might get some more attention when we get a bit more. I believe we currently have 3 minigames which isn't allot.

It might be nice to look at those: MCSmash by DiamondToaster, HungerGames and Paintball by me. If you're going the same way as I did with arena state's I advice you to split up the file a bit. A player management, team management (might not be needed), storage management, etc. Though 600 lines isn't allot normally it would definitely make things more organized.

There are some difficulties with the way you want to set up an arena.

Switching/rotating through different schematics would be pretty cool, but could also cause lag (in the client ^^). Also, you'll have to detect the arena floor where the player's actually remove the blocks.
