Picking a Culture for ability scores

Raios is a game-system-agnostic setting, but this format and these ability scores are used first because they are such a common map to various roleplaying games and second because they should easily mapped to other ability score systems in other games. As is surely already often done by players of those game systems.

When your game system, GM or table handles ability score modification differently, that handling supercedes these rules.

Culture and ability scores are not absolute; these are adjustments to a character's starting ability scores.

Humans are the baseline for ability scores, and so offer no specific modifications. Some game systems also give human PCs a choice of ability score modifications.
