I've been playing during the stress test, and honestly didn't think I'd like the game that much, but 5 hours later, and I'm somehow still playing.. and think I want to keep playing even after this stress test is over. I was told a beta key was the way to do that, but didn't quite understand what they meant by persistent beta? Does that mean, the game is just going to be available to play while it is still being worked on vs. it being closed off until a "launch." Essentially, what everyone seems to do these days on Steam with early access games.. like Project Gorgon is an example I can think of.
