Thanks everyone for your questions! Submissions are now closed. We've had an awful lot of questions asked that we'll now sift through, and hopefully we'll get the answers for you sometime next week. Unfortunately given the number of questions, there are some really good ones that we'll have to pass on, but that just means that the ones we do pick will be excellent.
Please note that WePlayCiv is still accepting questions here, and Apolyton hasn't started yet, so look out there for another opportunity.
I think that you should publish a list of questions sent to Firaxis.
