As someone who's been with this series since Diablo 1, I have to say I'm rather disappointed with some of the changes they're making.
Someone mentioned the guy on the aircraft carrier, well I work on a submarine and I can tell you I know of numerous guys on subs who are quite disappointed in the inability to play Diablo 3 together underway.
I think this RMAH is completely stupid too. But then again I'm someone who, in Diablo 2, never duped, or bought items, or participated in that whole culture at all.
My fondest desire would be to have offline single player, and ideally LAN play and the ability to host/join 4 player games without any sort of interraction with battle.net.
I played the free beta weekend (because despite putting like 7 years into WoW, and being a loyal Blizzard fan since WarCraft 2 I can't seem to ever get into a beta, no luck at all haha) and I really enjoyed it... they've done a great job with the presentation, the gameplay... I just wish it didn't have to have these lame developments attached to it.
I really do miss the days when PC gaming was more simple, without all this money-grubbing, unnecessary internet element... excessive DRM and pointless attempts to stop piracy at the expense of the legit customer... it's getting worse all the time.
What happens if the world plunges into chaos and anarchy, zombie apocalypse, but you still want to play Diablo 3 with your 3 wives in your underground Mormon compound? What then huh? Out of luck, I suppose
But seriously... we can all have disagreements, and should be able to have a civil discussion. But the group that always puzzles me on things like this, and they are unfailingly there for every thing like this... are the people who not only will support literally any decision on the part of developers, publishers, etc... but will lash out quite viciously at anyone who questions them. Even when the decision is transparently odious and completely out of step with previous entries in a series, or the way games have been handled for decades.
They seem to get some weird thrill out of being big old douches toward people with legitimate gripes about very worrying trends in the game industry. Puzzling.
