Yeah! That sounds great, if rules get clarified enough, I can probably just hack my own Solitaire variant, plus, adding a trading variant to a game already so focused on travelling seems natural.
Ah, sweet, sweet terraforming. The joy of many a player when they realize regular base-building just isn't enough in sci-fi. I think the Infrastructure section did a good job on background terraforming already, but having the crew participating via Decaoperations can definitely up things a notch. And I do agree that base building needs to be expanded, so far we have the economy and law levels, we have the industralization and biosphere levels, we have immigration and government changes, but what exactly gets an abstract colony from huddling in a regolith cave to having sushi dinner in a hyperloop definitely deserves an expansion.
Although I wasn't quite expecting that there can possibly be an Earthside era in a space game, having a few twists instead of the original Exodus is always nice (now you can have branches of histories on top of your branches of histories), guess I'll have to wait and find out!
