If you're developing a game, that game will consist in large part of rules. Those rules have to cohere and avoid contradiction. As an avid gamer, an experienced writer-of-instructions, and a lawyer with a knack for finding gaps and loopholes in rulesets, I can help you thoroughly map rule interactions to fine-tune your design, prevent conflicts, and reduce ambiguity. (Alternately, if part of the point of your game is having the players argue about the rules, I can help you find the most fruitful ambiguities.)
