I'm looking forward to what you add going forward.!
For Stress, if you're familiar with the module, it was 1d6-1d8 inflicted after a resolve save for each new encounter with the Meteor-mad colonists. ~1-3 checks per room depending on their interactions. Severity depended on how "unnatural" the NPCs were. Direct interactions with the module's "bad thing" were 1d10. Overall it felt like there were quite a few lucky rolls with passed saves and low stress damage.
On another note, I was wondering how you rule firearm combat inside spacecraft. We did have a shootout inside of a lander module as part of the finale. With no to-hit rolls in most MotO games, I just wasn't sure on how to incorporate thar additional risk of collateral damage without it feeling forced or excessive.
