Then why can't I connect :(Probably. They really need to get an uber server, and have multiple servers.
I don't think that'd work well if its supposed to be an entire world.
It'd be better for a very good server, methinks. And many people don't get on anyways. From what I've seen there's usually 200-250 people on average. Most villages have groups of around 5 people, so that means, like, 35-40 villages. So, why waste money on multiple servers for few people when you could spend less on a very good single server that could hold 10x the people.
I hope they do that, get a better server n' all. :o
