So far, the devs have been really good at trying to ensure saved games continue to work! Beta 9 saves should still work with the EA 0.1 version that is out now, for instance. But if you wait for several major updates, they often won’t work due to how many things have changed.
I was wondering if I should continue putting so much hours into my save game file. Haha Wanted to build my Empire, but if I have to start over… Well… Then Ill just casual play, and not be on TRY HARD mode. LOL
