Diablo III was released this morning at 12:01 PST. I stayed up and tried to log in but servers were busy. That was 2:00 am my time, I had a big nap. After 30 minutes I gave up and went to sleep. This morning 6:00 am on the second try I am in and playing with no problems. Others seem to be having some issues as Google Plus is full of error 37 (Server Busy) jokes.
I played the beta that went through the first chapter. I have passed that already in a couple hours of play this morning. I admit I like the archer character so far. I played the wizard during the beta and that was fun too! A more in depth review after some more play!
