So, Pathfinder has a great many optional rules systems that I love, like the expanded fear system in Horror Adventures and the downtime rules in Ultimate Campaign.
So, with the basic framework in Starfinder being very similar to PF, I'm wondering how much work each system needs to convert, in no particular order.
Now, I think the Fear system is one of the easier ones to adapt, as it mostly just expands on the situations that can increase fear, as well as the number of statuses. I daresay it needs no conversion at all.
How do you think Downtime (or any other system you like) would fair in Starfinder?
