Aaron Griffin SWvM has, by default, no “traditional” sci-fi RPG roles — it’s space emperor, space jesus, love triangle, faction lord, alien, and spy. It is exclusively gonzo bananapants weird shit, with the closest to “traditional” classes being the Spy, I would say? But even that is stretching the definition of traditional, with its Master/Spymaster tension. The text calls out that you can use the traditional playbooks, and gives examples of Space Fantasy Bards, Rangers, and Wizards, but those are just reskins rather than whole new classes that are overlapping with other stuff.
