Dragon Quest IX: Sentinels of the Starry Skies is one of the biggest games on DS, but you may not realise exactly how big until you read this.
Committed player Steve Tolin has seen all there is to see in the Square Enix RPG: he's defeated every enemy type, grabbed every item and piece of clothing and found every Alchenomicon recipe too. He's finished all the downloadable quests and has done it all in single-player mode.
How much time does such a mammoth undertaking require? Tolin clocked the game at a remarkable 773 hours or 32 days of gameplay, with only a single minute spent in multiplayer, presumably by accident.
Interestingly, Tolin is also the owner of game developer Deep Fried Entertainment, whose game Shadowplay hit WiiWare last year.
