Gameplay and gameflow Probably the reason why it's been taking so long to be developed in the first place is because it's hard to make D3 "fun". And new. Diablo 2 was a monstrosity from the developers - it was *continually* being overhauled and very fundamental changes were made to the gameplay. The most significant of which was probably the skill system - iirc that came very late in development compared to the rest of the game. But lo - the system was a success. Rightly so... but balancing was a *****. (how many patches???) What I'm trying to say is, designing the gameplay is Diablo 3's main hurdle. What functions do the skills have? So far we've had passive boosts to damage/speed/armor/resistance/whatever, melee/missile/physical offensive skills, summons, traps/totems, offensive spells (think sorceresses), teleport/leap,... D2's skillset isn't all THAT varied. I'd look to DotA for examples of other functions of skills. So, what sort of gameplay changes are you expecting? Gameflow is another. How do the monsters behave? How are the fighting dynamics like? Seeing as how quick reactions were critical to survival in D2 at higher difficulties anyway, could we expect the gameplay to flow a lot quicker (thinking DMC or Kingdom Hearts)? Or just more of the same? What sort of advances do you expect in the gameflow?
