Paizo fully intends on supporting Starfinder with a monthly Adventure Path, where subscribers receive pre-written adventures on a steady basis, similar to what they do with Pathfinder.
Starfinder, a new IP created by Paizo, will serve as the sci-fi equivalent to their popular Pathfinder franchise.
It’s likely Paizo will end up releasing supplementary rulebooks for Starfinder, though there’s no concrete evidence of it yet.
The Adventure Path will also include new rules and new monsters to tinker with.
