Crafting

A Starfinder character might want to spend a significant portion of their downtime crafting. This can mean repairing and maintaining their futuristic gear, such as making ammunition and using archaic tools like waterwheels to recharge their batteries. It can also mean figuring out how to upgrade their gear without access to AbadarCorp's free online shipping and many convenient locations. Doing so could require finding an NPC who can do the actual checks behind the scenes while the PC is off on adventures, especially if the PC doesn't have ranks in Crafting. It could also mean working alongside another PC, perhaps allowing the Starfinder PC to help the NPC Craft by teaching them the basics of the advanced technology. You might even find yourself limiting a player's access to higher-level tech gear by forcing them to find necessary materials, from rare minerals to Numerian artifacts, that require specific adventures to acquire!
