I’ve got shelves full of Call of Cthulhu, Star Frontiers/Traveller and Champions modules that I’ve never used.
I know Jason often uses World of Dungeons to run trad or OSR modules and Tom uses a variety of different indie games to run them:
What would you suggest for running trad modules from Cthulhu, Scifi or Champions (or other supers as I think I’ve some V&V sitting around too)?
I’m a big fan of Cthulhu Dark for horror investigations — currently using it to get through Masks of Nyarlathotep and it’s holding up well.
If you are after a gamier system, The Cthulhu Hack has your back.
For SF, Offworlders is functionally WoDu in spaaace and plays nicely
It could be interesting to string together modules from various settings and systems using World Of Dungeons Turbo: Breakers as the basis. Each module would be an incident zone.
