Coming off the back of numerous connection issues with Diablo III, Torchlight II will be holding a stress test beta this weekend. You can sign up to help lay on the stress at the game’s official website. That should mean less Error 37 come the game’s release, then.
(Just for reference; Torchlight II is very similar to Diablo III, hence why we compare the hiccups. We’re not just trolling Diablo III, honest.)
