I’ve played through the open beta for Diablo 3, and there is alot of thoughts going on now within me.
Probably the best read about the difference between Diablo II and Diablo III could be found here. While I personally think that the change is pretty drastic, I am also incline to reason out that these changes have been made to assume that every players will be playing co-op games. And they probably have that in mind and start thinking through the game plays from there.
Like it or hate it, the story should be nothing short of epic. A newcomer might take it as it is, while a Diablo II gamer will find it hard to accept these. I for one, would hope that every class is balanced out and I do hope that that the PvP system will not limit to 2v2 system only and take into account more team plays mechanics.
