Relevance for Games

When you're creating a group that has its own culture (such as the Marines or a prep school's students), or an alien race or species, that group, to be interesting, needs to be composed of a colorful grouping of Traits.

If the group or race has too few Traits, it can be boring. The same problem occurs if the grouping of Traits isn't interesting enough. As with the creation of a character, the grouping can't be cliché (one we've seen before).
