I've long wondered why the thriving community around Minecraft doesn't get behind Luanti or a similar open source "clone", especially since so much of the community stuff itself is open source. I fear this may be a painful lesson for those people that open source matters. It's not the license cost (aka the free as-in beer freedom) that is the problem, it's the free as-in speech that is the problem. If you don't use software that respects your rights, don't expect it to respect your rights. All you can do is pray they don't alter the deal further.
There are a lot of similar implementations, but nothing really comes close to replicating the full mechanics of the actual game. Probably because the game is so easily decompiled that most people don’t see a need.
I wonder what it's like: opening one's mouth and hearing things being said, without a moment of thinking before.
Maybe it's like riding a talk-bus I suspect: when you see the bus turning the wrong corner, you realise you're on a looong way back home suddenly, because the next stop is the nowhere station.
