I'm currently designing a campaign that has a monumental amount of in-game variables to keep track of, which I'll need to check every time a certain kind of event happens. Reducing the number of these isn't an option (they're all necessary for the setting) but I also don't want to take five or ten minutes to check every rule anytime one of these events happens during a session, since it bogs down play. What are effective methods of keeping track of these rules without bogging down play?
The campaign I'm planning is a "closed circle" sort of deal, with every area prepared beforehand. All of the variables I'm keeping track of are specific changes that happen in certain areas on the map. The entire basis of the campaign is figuring out the secrets it functions on, so to do that, I need to keep it consistent.
