I seem to do this a lot - I’ll find a game whose setting I really like, but dislike the ruleset it uses, so I end up converting it over to the ruleset I prefer (usually Cypher System). I’ve learned that to some people, this is blasphemy of the highest order, which is surprising. I still do it, though. 😬
Greyhawk is far and away my preferred setting for D&D-like games, I’ve run a bunch of rules in it but mostly 13th Age and Shadowdark.
Did you find it easy to make the switch to those game systems?
Yeah they both are built around the classic D&D gameplay loop of exploring and dungeon crawling. I run my own adventures rather than using purchased modules so I don’t have to worry about converting monster stats and stuff. But Shadowdark converts very easily to old D&D versions, it would be straight forward to run any old pre-3rd edition D&D modules in it.
That sounds really cool. I’ll have to check that out. Thanks!
