I paid the extra $20 to get into Diablo IV early access, mostly based on my years of history playing all the previous Diablos. It's one of my all time favorite franchises.
I got 2 good hours Saturday to play. Then the rest of the 4 extra days, the server was down, then up, then down. Why? Blizzard somehow thought it was more important to fix a bug in the online shop than it was to let pre-paid customers play all 4 days of their extra time. God forbid someone couldn't buy their phony cosmetic armor look that has zero effect on gameplay.
I won't say "never again" because I've done it before. I'll probably... oh wait, is that another shiny!?
