I've been playing around with Waninkoko's save game tools which is great, but its a lot of hassle to backup/install saved games, especially if I want to take them to a friends place where running homebrew might be a bigger hassle. So I started looking around the saves and this is what I've got...
if they get permission from 4j (the studio who helped put minecraft on consoles), they could put the console edition tutorial worlds in the game, as seeds
and i mean all of them (if not, maybe a few highlights, like TU1, TU31, and TU69)
