Dealspwn: " If one considers the history of Diablo, to acknowledge its place as a bastion of singleplayer (or local LAN co-op) magnificence, this always-on internet requirement seems all the more frustrating. There will be those who were looking for a loot grinder to play in all weathers, in all situations, and now that just can't happen. There are reasons, of course, good reasons as Jon has pointed out, and Blizzard should absolutely and unequivocally make the game that they want, but there's a shady side to this as well. True, the connected experience adds much to the game, but the flipside tastes of restrictive DRM, with that touted auction house hovering as a spectral elephant in the room. That's where Blizzard are hoping the real money is, and the only way they'll be able to push that is by keeping online player retention high.
Yet as with most outcries in this industry, the prevalent sense is that none of it matters. Games will continue to be released with crippling bugs, players will continue to moan and bitch before shutting up and handing over their money. The most sinister aspect is what Blizzard's always-on requirement means for forthcoming games. Will this lead to more restrictive measures from triple-A titles and larger publishers, knowing that they can implement whatever the hell they like without fear of repercussions in the sales figures?"
