MMO developers. You must have an addictive, enjoyable, playable game. All of Blizzard's previous games fit that criteria, and it's the reason why the original Starcraft, Diablo and Warcraft games are still played to this day. Polish the game enough before you release it, don't start polishing after release, all the reviews will be bad; make the game as perfect as possible and you'll have people playing for years. Edit: Lol, so this is where Zaeed went.
Following from my previous comment; I have lost faith in Blizzard.
They haven't made a good game with Diablo III, they've only made a pretty cash cow - you'll know what I mean once you reach inferno.
