I live in Irvine and my friend knows one of the game developers at Blizzard. He was telling us that in WOW, the world is so large, that if there were no obstacles that you could run a character from one end of the world to the other end of the world in three days. Sounds like a pretty large universe to me!
I asked about Diablo 3 and he said they weren't allowed to talk about projects that were being developed. (I'm assuming this meant that they were working on it!)
I'm gonna try to convice the guy to give me a summer job testing games. It'll be a great job since I'm a technology teacher and I get summers off.
