This
weekend on Steam, the new release (released this spring) Sid Meier's
Civilization V is a whopping 75% off, bringing the price down to a quite
lovely USD $ 12.50 for all of your turn-based, winning the world
strategy needs.
Also on special on Steam is the Need for Speed franchise, ranging from 50 - 75% off.
On the Impulse Network, the Theatre of War, Company of Heroes, and other
games are on special as part of their strategy game sale; over at
GamersGate the ArmA series seems to be on special as well, continuing
the military game trend. On Games for Windows / Xbox.com, Need for Speed
Shift is on special, if you prefer using that site over Steam.
It seems the best value to be had here is the Civilization V special on
Steam, considering the original price was $49.99 and it was just released
this spring - this is not a franchise sale, this is not an 'in
preparation for a new game' sale, this is a sale of a fantastic
turn-based strategy. But there are plenty of other games to be going
around if you are not keen on that Civilization V, judging from these
sales!
