Every time I unlock steel I feel like I get stuck. I have spaced out and I love it but I’m usually stuck to my first two planetoids because I hate the way I built my base but I don’t have enough resources or physical space to rebuild everything before I can start doing more rocketry stuff. Any advice?
If you play the “classic” version of spaced out your main asteroid will have more resources and let you take a bit more time through the mid game. The other version really wants you to do rockets quick. CO2 and/or sugar are good for early game.
I usually keep a full 2nd colony on my secondary asteroid so I have full access to those resources too. My supply teleporters are always working. Your secondary asteroid should also be on C02/sugar rocket round-trip range. That can move dupes and/or loads of storage containers. And any asteroid with a co2 geyser can be a refueling depot.
