Changes

**In Jaden's era, litteral school were founded to ''teach'' the card game. Being a [[Duelist]] is now an ''actual'' job, with a Pro League like any sport.

**In Yusei's era, the game has become integrated into almost everything. From security puzzles, Duel Disks forbidden to certain citizens, Duel Runners being created and even officers of the law being mandated to have a Deck to give criminals a chance to win their escape.
