Me and my cousin (up for thanksgiving) have been playing Minecraft on my Xbox, which i rented from gamefly, but we're thinking about buying it so we can play together even after he goes home. At first We were going to just get the xbox version but then i decided to look into the possibility of getting it for PC, I was thinking the world was bigger and according to stuff i found online its 30million blocks wide or something... which just sounds like much more exploration opportunity's than the xbox which is supposedly ~8502 or so.
What I'm curious about though is making a private server. I want a place where we can do our thing and not be bothered by anyone, but also have the ability to invite other people we know. I saw other sites talk about downloading a jar and hosting it, but does that mean that if I were to download the thing and host the private server he wouldn't be able to play if I wasn't on?
If anyone has done something like this or knows how to set up a server that both of us have access to but nobody else (maybe a password or something) I would really appreciate if you could take some time and explain this to me. I don't really know where else to ask this kind of thing and wording it in a way that Google can help me is tricky.
