Dont diss the beds!If you found the free, outdated version fun, you might as well find the 'finished' one better. If you played the free version on the site, it is completely different from what you got. You don't get all blocks and just build random stuff. You generate a world with an actual bottom, where it becomes a survival - unless you're playing on peaceful, then it's just free-play until you get bored. Now, if you had played a 'pirated,' outdated version and you liked it, then it does get better than that.
Played for four months straight and got bored, though. Notch just wouldn't fix the Nether in MP, so I eventually gave up. I wanted to have something different to do, and he gave us beds.
They let you skip Night time!
