Is there a game that is great for the SciFi trope of “show up in a new place, try to understand the differences between there and home, engage in diplomacy or warfare, and return”? You would want the tools to map out the galaxy (/dimensions) through your “travel” moves and roles that let you do moves related to diplomacy/research/firefighting/etc. There are probably other forces doing this travel and some of them present existential risks. (Think Stargate SG:1 or Sliders, for example)
Uncharted Worlds?
