Languages can add a lot of interest to a game. The current OSH rules assume that there is kind of one language, a common language, that everyone knows. Here is a way to add a little depth without a lot of complexity.
Characters are fluent and literate in one additional language per Awareness bonus point at generation. Adding bonus points later through advancement does not increase languages known.
Characters can choose to learn to be fluent and literate in a new language instead of accepting an attribute point when they level.
This language system is fast, it’s easy, it allows characters to learn languages in the course of their travels, and it adds functionality to the game world.
