And that's where single player commands/world edit mods come in XD
A total of 3 commands and you can fill a selected area with any block... actually you can do that with command blocks I think.
But wow dem sticky pistons sound awful, no fancy hidden doors for you
SGH: Sharing the screen is half the fun for us. We don't play against each other. We play together. And I have a 42" TV, and honestly, even though we work together a lot, if we go do our own thing, Neither of us notice what the other player is doing. I mean yea if we were playing against each other you would just look at the other side of the screen, but we play together.
