Diablo III is more. More action, more death, more skills, more colour, more story, more beauty, more top-down, click-hungry, loot-happy, fast-paced, over-the-top, randomly-generated, fantasy-horror slaughter. Eight years after the last instalment in Blizzard's classic action-RPG series - probably ten, by the time it comes out - Diablo III is more of the same. Beneath the waves of excitement generated by its return - in the form of twenty stunning minutes of game footage - there is the slightest undertow of anti-climax. Is 'more of the same' really all there is to it?

Blizzard's chief design guru, Rob Pardo - formerly lead designer on World of Warcraft - argues that traditionalism can't really be a sin when no-one else is upholding the tradition. "If there were a ton of games out in the market that are the isometric action-RPG model, then we probably would have more seriously done a different approach," he says, pointing out that two Blizzard "splinter groups" - Flagship and ArenaNet - have already chosen to take "Diabloesque" gameplay in new directions with Hellgate: London and Guild Wars. "But it just always amazes me, with a game series that's as successful as Diablo's been, that I don't feel like there's a lot of great competing games in that same genre."
