Civilization 5 was a masterpiece of sorts and Beyond Earth iterates upon the concepts brought to Civ5, adding a few things that are quite interesting and still creating the perfect 'one more turn' experience. You have more control on the direction your civilization is taking with some more customization features that impact gameplay in semi-significant ways and you have about half a dozen ways to victory. It's one of the rare games where I just started playing and emerged from a 8 hour session, only after victory was within my grasp. This was on very easy, but oh well.
