Dungeons & Dragons groups used in schools as extra-curricular alternative to sports will make exciting new arenas for game-play development, campaign development, teaching economic systems theory across cities, and offer epic rewards in high-level tournaments. Higher-level "Game Masters" (or GMs) can keep track of XP totals, like economists keep track of RL currency in circulation, so that they are comparable across regions. Holographic EQ cards (with serial number) can be traded to keep highly-prized items valuable and the game-world can be developed in a balanced, in-sync manner.
Each DM group can create their own figurine, with higher-level regions having larger figurines. These can be kept to oversee game-times to signify that official rules for XP and EQ generation are in-play. Game play can take place in the school theatre, where community members and others can watch. The stage offers the dark curtains to hold the game space as well as music play-back to create atmosphere.
Mana can get awarded in tournament-play to the DMs, churning the city-machine-state into motion to produce goods (made by your craftslans), which are tradeable across cities/regions. The DM can also decide to turn it into coinage rather than equipment. In this way player cities can experiment with the idea of being industrial generation centers or developing other values where value is stored in money. Any out-of-game equipment trading should get taxed by the DMs who should collect like 10% in gold for getting greater equipment inventories.
