Vanquish is the game I always reference anytime the idea of a game's worth being tied to its length is brought up. Yes, Vanquish is brief, and you can probably roll credits within 4 or 5 hours on a first playthrough, but those are some of the most action-packed and intense hours you'll spend with a game. The pacing is amazing and nothing overstays its welcome. It won't take you long to beat, but give me a game I'd like to play over and over again any day simply because it's that fun.
