So here's the deal. We never (AFAIK) prohibit developers from patching/updating games they've made. If the Stalin vs Martian (yes we published that...) devs wanted to do a free update, patch, expansion, DLC whatever - we wouldn't stand in their way. If they want to spend their time and money supporting the game there's no reason for us to stop them.
The game was released in a crap state - since then patched/updated - big props to the developer for that. Today it's in a better/more playable state that we're calling "good enough" - which is supported by the player numbers - a lot of players are spending hundreds if not thousands of hours in the game.
Could the game be fixed up even more? Sure it's software after all. Are we going to fund additional patches/updates? No - we're still far, far in the red with this project - we made a huge investment into the development and things didn't quite work out. So we're focusing on other things now. Are we in any way standing in the way of the devs or the community patching/updating the game themselves? No.
The simple fact is, that there is 0 money to be made by Kerberos for finishing and improving SOTS2 now. They have washed their hands of it and moved on to new games that they can make money on. So unless some savant modder comes along and takes it up. This is the broken version we are stuck with.
