Civilization V has received its first major update today of what's likely to be the start of many bug fixes, tweaks, and enhancements to the game. The series has always be tinkered with over its life and been supported quite well by the developers based on community feedback, and it looks like Civ 5 is going to follow that tradition.
Also out next week will be the first batch of DLC for the game - both of which were included with the deluxe edition. The Mongols Civilization and Scenario Pack and the Babylonian Civilization will be available for download. The Mongols pack will be free while the Babylonian civ will cost $4.99. I've used the latter in my campaign already and can say they are excellent if you are going for a science victory. This also makes them an excellent civ to use in co-op since all players get the science bonuses.
