Consistency, consistency, consistency!

One of many things I've learned about grammar and editing is that there aren't as many hard-and-fast rules as your high school English teacher might lead you to believe. But while many things are permissible, that is not a license to abandon all rules. The key is consistency. If Webster has "mind-set" and you want to spell it "mindset," most people won't question you—so long as you are consistent.

This example may seem silly, but the same principle, I've found, applies when teaching board games and especially while writing rules for a game. Consistency is key, and there are few things more infuriating when you're trying to learn a game than inconsistency.
