The publishers of Nightfell, a horror/grimdark setting for 5e, made a post on Reddit announcing their kickstarter for a PF2e port.
The setting looks interesting, and it's well reviewed on DTRPG. It's also received ongoing support since release. So, I'm a little excited about established 5e 3PPs dipping their toes in the PF2 waters, rather than just slapping a new name on the 5e mechanics and launching "their own" system.
It kind of feels like the game is approaching a critical population limit, where 3rd party support will be more common, and projects supporting both systems will become much more normal.
