I think there would be more people playing the GotM if there were some kind of reward. I'm not exactly sure what the reward could be, but I don't think it should base on wins and losses since GotM is about playing new games - not necessarily about winning.
Maybe we should reward the person who plays the most GotM games in any given month.
Part of the trick is how to reward someone. Cities\Guilds can not directly give Talers to people. I don't think random lotteries within cities are allowed (but I will dlb check). Too many ways around it. Taler rewards for tournys are usually given to the city and not to the player.
The council is working on a few new ideas. One day tournaments, for example. I'm going to give the GOTM idea a break. I'm sure this will come back someday.
