Just played my first game with a scenario last night. Ancient Rivals, 4 players, 90 seconds per turn. It's quite nice to be able to finish a game in one sitting, although there are some oddities with the gameplay (50 turn limit means harvesting forests and resources is almost always correct) and your starting civ/location has a big impact on the outcome. But it was fun, I would definitely do it again, and it's nice to have the option of getting online and finishing a game in one sitting.
