Much as I like the game, even in it's alpha stage, I find the servers to be rather frustrating. Not the way they're run or the interaction on them, mind you, but how they'll go offline, permanently. It's happened about five times for me now. After taking the time to locate a server with a decent ping rate and capacity, and then spending weeks getting myself established, they'll just up and disappear. I guess I should just stick to single player.
