Gender Neutral Instructions: Talk about everyone

If you can’t talk to the reader and you can’t use a specific example, consider that you’re probably talking about a group of people.

“If a player should discover this trap door, he should make a Learning roll to understand the runes. If he makes his roll, he understands that it insults American tourists.”

“Any player who discovers this trap door should make a Learning roll to understand the runes. Success means the player understands that it insults American tourists.”

“Players who discover this trap door should each make Learning rolls to understand the runes. If successful, they understand that it insults American tourists.”

It becomes useful to go from “talking about everyone” to “using a specific example”.
