First of all, great game, i loved it, one of the best colonization games out there (not enough in my opinion...)
The only thing i can say i wished for was, as many others have said already, is a sandbox mode, but anyway, i was hoping to know if there is some way to stop the last mission from advancing to an end, like in a previous one where if you didn't check the destroyed colony, you could go on forever...
Because the last mission is the most free ended i can see...
Thanks in advance.

You could technically keep the last mission going forever if you never defeat the invading forces. Keep one enemy planet alive and you can continue onwards
