A few noobish questions I hope you old timers can help with, I could Google but the results could well be a tad random. I first tried Minecraft last year, downloaded a "free" build which seemed to be a relatively early version, was enjoying it lots then realised it perhaps wasn't entirely legit, so I bought it and thankfully (though I wasn't overly bothered) my world/save remained intact.
I think I updated the client, to some extent at least, as I don't think I previously had a few things like cats, villagers etc (though yet to meet any villagers)
I like the game a lot and played it what felt like tons in Survival mode but because I got it relatively late, was way behind most of the current gamers, modders and whatnot.
However, watching series on Youtube like that of the excellent "X" I felt there was still tons to do with my relatively vanilla version, and had read others lament all the changes that have been made over the years.
Anyway, onto my questions:
1. Having not played it for most of a year, it is now asking me if I want to update, as I currently have build 1.4.6. I take it this will not affect my world in any way, just add more creatures and features? But if I create a new world are there some differences in geography/geology now? I remember reading that mountains etc are less spectacular? Why?
2. Did I also read that the most up to date version lets you roll back to a previous version anyway?
3. I'm trying to get a friend into it and want to play multiplayer, but ideally just the two of us for now. She has a Mac, and me a PC, can we inhabit the same world, and would this world need to be hosted on one of our computers? Or do we really need to find a more dedicated server? My PC is fairly nifty, I would say.
4. Less important question, I noticed in the xbox demo that I started with a few things like a workbench, which seemed a shame, much more fun to hit the ground running and craft such things from scratch. Do the more recent releases hold your hand like this? If so I would advise her against it, then perhaps update when she is settled in some.
Hope you guys can help with some of these questions =)
