It's the normal length for a campaign these days, 8-10 hours. I can't think of a TPS or FPS that took me longer than 10 hours in the past few years, 12 hours tops. They all fall into that 8-12 hour length, dead space, resident evil, tomb raider, killzone, castlevania, enslaved... vanquish was shorter, around 6 hours, still one of the best games of this gen though. Rage is supposed to be longer than your average FPS, close to 20 hours. Around 10 hours is fine by me if it's a good campaign, specially when there's also a multiplayer mode that I'll be playing for more than 50 hours like in uncharted. Well worth the price of admission.
