I think we should make a nether world. I know theres a way to make it work in multiplayer. Personally i <3 The nether i was thinking we could have an event when the world opens and everyone goes in. We could make a city in the nether! Tell me what you think i'd love to hear your ideas!
Im sure there are loads of reasons not to have a nether and im happy the way the world is currently now =]
