I love the Genesys system because it's designed specifically to homebrew any genre of setting you want (including custom magic systems), along with multiple official settings.
It is so easy to take NPCs, items, etc, from fantasy to sci-fi to current day, to post apocalyptic, etc. Since the rules and stats are intentionally setting agnostic.
And I absolutely love the narrative dice system.
If OP likes plating a variety of settings it's worth checking out. Or one of the billion other games out there
To be fair, I think he's just regular fluid
