Megagames Crack [better] Online

If you meant something else by “megagames crack” — such as a design challenge in live-action megagames (e.g., a “crack” in the game’s mechanics or a critical rules exploit used for strategic advantage) — please clarify. I’d be glad to help with a legitimate report on game design, rule exploits in megagames, or how facilitators handle broken mechanics in large-scale participatory games.
