Fastest?? Portal obviously. Took around 2 hours.
Yeah, but Portal was meant to be a short game. A very fun one, mind you, I did it in about 2 1/2 hrs (two sittings, because I'm capricious).
But Force Unleashed I & II... repetitive (albeit cathartic, to an extent) gameplay and hideously short. Borrowed a mate's copies (because I'm so disillusioned about StarWars games except KotOR I/II, even Battlefront bores me) and finished both in about 10 hrs and ended with a feeling of 'I wish I had played AC:B instead'.
Only other one that comes to mind is (sic) SW: Republic Commando, 'twas OK, finished in a little under seven hours, ending pissed me off, though.
