If you missed the recent Steam offer to grab Civilization: Beyond Earth for cheap, then you’re in luck. Gamersgate have brought down the price once again to (almost) the £20 mark, providing a saving of around £6.
While it definitely a Civ game, it’s an entirely different beast thanks to its free-form technology tree and much different pacing towards victory. However, those that take the time to get used to the changes will find a rewarding experience. You’ll lose hours to the addiction, though, but you knew the risks already.
