Looking for SciFi Game

Hey all... I'm getting back into gaming after being away for some time (like decades).  I'm trying to track down some good SciFi games.  I see some Starts Without Number and StarFinder games here, but they are mostly at times I can't really play. So: 1. Is there interest and a GM for a SciFi based game (other than Star Wars/Star Trek/CyberPunk) that could play Sun/Tue/Thur after 8:00p CDT (GMT -6:00) or Mon after 9:00p CDT? 2. What other game systems could I search for on Roll20?  I've looked around at Starts w/o Number, StarFinder, Gamma World.

Does a Fallout-style post-apocalyptic game using a Pathfinderized version of d20 Modern sound up your alley? Because I might be opening one as my flagship campaign.

Yes, fallout style sounds really cool.  I haven’t playedPathfinder rules, but think I can adjust quickly.
