Skills

Most Pathfinder adventures won't include the Computers or Piloting skills, making options that rely on these skills superfluous on the surface. Options that grant training or boosts in these skills should instead use other related skills, such as Driving Lore, Sailing Lore, or Survival for Piloting and Crafting, Mathematics Lore, and Thievery for Computers. Allowing your characters to use Piloting to Drive any kind of vehicle might help simplify games that heavily feature vehicles, but be cautious about encouraging the Piloting skill if you don't plan on featuring vehicles in your campaign.
