While reading another question I was introduced to the notion of a D&D tournament.
According to the wikipedia article on the D&D Championship Series, the basic idea of these tournaments is that there are multiple tables of players and GMs. The players can choose a pregenerated character and each table runs the same game each round.
Players are somehow scored on their performance. Wikipedia doesn't describe this, instead saying:
The exact scoring system was kept secret as the scoring may reveal secrets to be discovered in the adventure, as well as to encourage players to play to the spirit of the game, not to the exact scoring checklist
How were players scored in these D&D tournaments? Although I mentioned the D&D Championship Series, my interest is broadly in D&D tournaments – that's merely the only example I currently know of.
