Are you kidding me Blizzard? Are you SERIOUS?! I have to be online AT ALL TIMES to play Diablo 3? We waited 10 years for this?!
This isn't the Diablo style of game anymore, this is just another MMO. Blizzards excuse for this DRM is "it authenticates all files and items blah blah blah." Cmon now, I can handle having to be online to activate a game, but why not give us the option to have "Offline mode" and remove LAN (like you did with Starcraft 2) and let us play through on our own, then force us to sign in if we want to play with other people.
Blizzard is becoming useless. It sucks, they were one of my favorite game companies. Oh well, I guess I'm buying Diablo 3 in a couple of years when it's less than $60.
