Batman: Arkham Asylum

It may not have a great big open world to play around in like Arkham City, but Batman: Arkham Asylum is still our favourite game of the bunch. It introduced everything that's great about the trilogy; the combat, the dark tone, the endless Riddler puzzles and detective work, whilst also serving up a story that didn't waste any time. Asylum is a tight and taut thrill ride, one of the all-time great superhero games and, over a decade later, it's still a must-play.
