It's probably been said before, but the game should be sold more actively instead of just on the basic site. I only found it after searching around about Capitalism 2 after playing it, and I've now played this quite frequently.
What I don't quite understand is why you're not also putting it on Steam, through Greenlight. There's no rule that states you have to have that as the only version, for the people who don't want the extra layer of DRM, but even throwing the game on there and, provided it gets the go-ahead, opening it up as an early access like a number of other games.
It's a shame to see this go so quiet as it often does and it would be nice to open it up to a larger community.
