My recent posts about the world of Masters of the Universe, had me thinking about how I would run a MOTU type game. Given the multiple canons, it's a matter of choosing and refining. This is what I've got:
Mineternia Plus. As I've discussed previously, the earlier minicomics included with the toys, before Prince Adam and before the Filmation cartoon (what fans call Mineternia or the "Savage Canon") place the action in a post-apocalyptic, science fantasy world with something of the aesthetic of 80s barbarian films, mixed with that of 70s barbarian comics. There have been a number of cool or interesting additions to MOTU since, and the world detailed in only a few abbreviated storybooks in a toyline is pretty barebones, so this canon would only be the jumping off point.
Sword & Sandal. MOTU has the mostly austere terrain and musclebound heroes of 80s barbarian films, but the world seems to call for a bit more "PG" approach, so I think another sort of musclebound hero genre is a good reference, the peplum film. Protagonists would largely be wondering do-gooders, like the Herculeses, Goliaths, Macistes, and Ursuses of these films.
A Sufficiently Advanced Technology... MOTU is science fantasy, but its tech (particularly if you discount the cartoon and some toy boxart) seems to be one-off rather than mass produced stuff. Even if we allow it's all salvage from ancient caches, it shouldn't be down to each individual with unique tech like it seems to be. I think MOTU technology is more like magic items (maybe it even runs off magic after a fashion). Individuals can only "attune" to so many items at a time.
More Henchmen, More Underbosses. The MOTU of the comics and the cartoons that follow winds up working like a superhero comics, where Skeletor and his cronies are defeated, but allowed to escape to fight another day--or in the cartoons occasionally put in jail! In keeping with a more fantasy fiction vibe, more henchmen would die. To give name villains more of a chance, Skeletor should be at something of a remove, and even his traditional underlings should command gangs. Taking out a name villain should generally be something of an accomplishment.
