Our colleagues at Polygon recently spent some time with Ed Beach, one of the people involved in the creation of Civilization V, and the lead designer on the forthcoming expansion pack Gods & Kings. If you haven't had a chance to play the game for yourself just yet, you're in luck. Both Steam and Amazon are offering Sid Meier's Civilization V: Game of the Year Edition for a whopping 75 percent off this weekend. That brings the total cost of the game down to just $12.49. Even better, Steam is letting users play the game for free up until this Sunday at 1PM PDT, giving you a little taste before you purchase. Both sale prices expire May 28th, so if you want to make sure you're able to jump into Gods & Kings when it launches this June, we recommend taking advantage.
