So far, Starfinder Society Scenarios have added:
- 3 languages
- 2 playable races
- 2 weapons (at least)
- Existing races legal boons
- Race improvement boons
- equipment
- many other boons to change your character and ship
I would think it would be reasonable for you to add this material and charge for it.Put a whole seasons worth together and it should be worth $10-$20. I would pay up to $20.
