Ok let me start off by saying that this is a decent idea but let me clear some stuff up first. The spleef world is a no because you don't need a whole world for spleef just an arena that you can build. The idea for a builder world is just plain stupid because there are already builder worlds. I don't know what you guys don't understand about the zones, but they are your worlds. The idea is for your guys to build to the theme since your are now high enough rank to be trusted. Once finished with a zone, you guys can decide as a group what the next theme should be as if we get enough people and the idea I'd reasonable we will make that theme. So here is what i suggest, if you guys really want an armory, I don't see why the next zone can't be that. Let me know if you have any questions.
