Are there plans to make the world (outside of your camp) permanent at some point?
There are technical limitations for this. The game has to be playable, stable, and have decent performance for not only the maniacs out there who stole a supercomputer from NASA, but also for their little bro who's playing on something that barely scrapes by the min specs. And that's even without factoring in the fact that we're also going to be releasing on consoles in the future, which means that *those* also have to be stable, etc etc.
