From top to bottom! (not counting patches): -Civilization V: Sept 21, 2010 (and 34 days later...) -Nebuchadnezzar: Oct 25, 2010 (and 5 days later...) -Craddle of Civilization: Oct 30, 2010 (and 47 days later...) -Spain and Inca: Dec 16, 2010 (and 77 days later...) -Polynesia: Mar 3, 2011 (and 61 days later...) -Denmark: May 3, 2011 -Explorers Map Pack: May 3, 2011 (and 100 days later...) -Wonders of the World: Aug 11, 2011 -Korea: Aug 11, 2011 From the time of this writing (02/05/2012) since any commercial release:178 days and counting. -Number of releases since launch: about 6. -Number of different releases: 11 (and about 3 bundles) -Average release time: about 54 days (not counting next possible release). -Shortest release time: Craddle of Civilization (5 days). -Longest release time: about now till whatever they release next (178 days). What to think of all these numbers, besides that I'm just doing this to kill time while waiting for STO to install?, well... that they have not released anything in quite a while (anyone could had told you that). But also that it's been about 3 times the average time since they have released anything or almost twice as much time since the Korea DLC.
