Heads up! Both Steam and GreenManGaming have Civilization 5 and DLC on sale! It's also a free to play weekend for Civ. 5 on Steam!! So if you've never played the series I highly recommend checking it out. http://store.steampowered.com/app/8930/?snr=1_quothttp_4__40
Maybe it is just me, but the non-expansion DLC for Civ 5 seems pointless. On the plus side, I am very happy to see a new full expansion coming out soon.
