IC for D&D 5E or Savage Worlds Campaign
I'll pipe up and point out there's lots of us Savages on site and I'm in no less than two SW fantasy genre games at the moment. Naturally SW is never going to be as popular as the current edition of DnD.
The point being I think you'll find enough interest in either regardless of the mechanics you choose, it's just that if you get X interested people for the SW version you'll get like 10X interested people for the 5e version, it's just more popular.
