How long does it take to play Portal 2?

Portal 2's single-player campaign is about eight and a half hours — an evening and a half, and one of the shortest games people still name among the best ever made. The original Portal is under three hours and was originally packaged as a bonus in a bundle of other games. The co-operative campaign adds roughly six hours and requires a second player. Puzzle games have unusually tight completion-time distributions because the solutions are fixed, so the spread here is far narrower than for any open-world title.
