Admit that you didn't have the funds to finish the game, so you released it as a beta, took the money from sales to fund the rest of development.
Everyone that purchased this total failure of a game has now become an investor, to help you fix something that should have had only minor bugs at release.
I've been a longtime fan of the Civ series since it first came out, but you just lost another investor.
Congratulations, you've made a ton of money on this game because of the name alone,but you've totally ruined it for a lot of people.
This is the current trend with game developers nowadays and it should be illegal for selling crap that doesn't work, or barely works.
