I have to start this with a warning, then a little tantrum, a few insults and a dash of paranoia. Apologies to those of you who already know what I’m going to say and are either fine with it or all raged out – you guys can skip this section. Diablo 3 can only be played online. You can play it on your own or co-operatively, but neither mode works when Blizzard’s servers are down, and neither mode is fun when Blizzard’s servers are slow. In my six days of playing it, I got disconnected twice and experienced unplayable lag five times, each time when my own internet connection was working fine. At times, the servers were down for hours.
That’s pathetic. There are valid reasons for forcing multiplayer characters to play online, but none for excluding an entirely offline single player mode. If you don’t have a connection you can reliably play multiplayer games on, don’t buy Diablo 3. Skip the rest of this review. Blizzard have chosen to exclude you completely, and I’m genuinely pissed off by the hostility and callousness of that decision.
For the rest of us, it’s worth knowing that the $60/£45 price for Diablo 3 doesn’t mean you’ll always be able to play it. The game itself would have to be phenomenally good for all this to be worth putting up with.
