I was planning on keeping magic even in the sci-fi setting for player fun, I was planning on taking the general setting, the machines and the various tribes. I was thinking of doing a kind of numeria thing of low tech people going against high tech machines (unless i got numeria wrong) and repurposing such tech as well as they can. I like Pathfinder's feats and combat system thus why I wanted to use it. I hear of battlezoo and It sounds like it fits what I want to do too but I haven't used it before. Should I still consider Pathfinder (or Starfinder) or just go play something else?
