Hi. I'm taking another look at CO after a long time away, that is, since CO1 on Matrix. I downloaded the core and was getting reacquainted with the game, but this thread had me wondering if I wanted to get involved and purchase additional modules and then try to keep up with everything, including additional upgrade costs. If I'm reading this right, then your business model would be like most other games. You buy the core game (or in this case get it free, basically as a demo) and buy the DLCs and that is your only cost. Updates/upgrades are free. That would make me as a potential new buyer much more comfortable.
