Kunovski: it will still have singleplayer (which you can play forever unlike the SC2)
SC2 singleplayer is going to end?
For me I'm not getting Diablo 3 sadly.
I don't have many things that stop me buying games (outside of an outdated graphics card) but the requirement to remain online the whole time in order to play the game, even in single player only mode, is one such factor that makes me not purchase a game.
I've never had a totally solid net connection and furthermore don't like the idea that I must remain online - must keep sending/receiving data - must keep using my monthly limit in order to play something that has no reason to be hooked up to the net.
I've no problem with onetime activations online and no problem with online based games which, by design, need online connections. But I simply don't purchase singleplayer games (or games with a component of singleplayer content) which demand my connection online in order to play.
Also - I don't actually mind the real money auction house in the game. To my mind its just adding the real life money transactions that go on anyway for things like Diablo 2 and other games; into the game itself and providing a safe environment for people to deal; rather than more risky out of game purchases and exchanges where its so easy to be scammed out of real money for the digital products.
So long as the auction house does not result in those with a natural trading talent or big pockets to leapfrog far and above those who cannot master nor invest as much real (additional) money into the game.
