Friends, Romans, countrymen, lend me your ears.
I come to bury Caesar, not to praise him.
The evil that men do lives after them;
The good is oft interrèd with their bones.
So let it be with Caesar. The noble Brutus
Hath told you Caesar was ambitious.
If it were so, it was a grievous fault,
And grievously hath Caesar answered it.
-- Julius Caesar, Act 3, Scene 2
Unlike Antonius, I bear no ill will. I have no axe to grind, and no reason to deny the developers of Diablo III their due & proper for those aspects of the game which actually do work well.
Don't get me wrong: I do think that Diablo III is a fundamentally broken mess. By which I mean that the developers failed to understand several fundamental concepts in game design, either didn't understand or didn't much care for the conventions of the genre of game they were making, and achieved an end result which fails on so many different levels that it's going to take a few thousand words to unpack it all.
But that doesn't mean that Diablo III is entirely bad. The game does do some things well, and it does a few things very well, and its only fair that I recognize the game's undeniable charms... before I start tearing it apart to see why it went so far wrong in every other respect.
And so, I shall begin my detailed criticism of Diablo III by praising it.
