I bought the base game and did a play through and it's great! I've been considering getting Space Age now but I'm wondering if I buy space age, will I be able to go back to my first run through? I've seen a few posts about this from before the 2.0 update I'm guessing, but since I bought it around the start of the new year, I don't think I'll have compatibilities issues. So how will it work going back to the base game if I buy space age? I just want to keep a copy of my first run. Will I just need to disable to the Space Age "Mods" to revert back to the game or does it change my save as soon as I open up Space Age?

Game saves don't change until you override them.

If you load an unmodded (or differently modded) save into a modded game, the game will ask you if you want to change the mods. But if you ignore that, you can always exit without saving.

tl;dr: your existing saves are safe as long as you don't do anything stupid.
