When you can't see the chart, some things aren't as obvious as they should be.
One of our players took to listing out our Obligations for the GM's initial roll. Someone pointed out that this person was being sneaky! He'd put his 10 points on the list first so that he had no chance of getting a double! He earned himself a double without a roll for trying to "game the system", as my GM put it.
Well, in thinking about it, that chart can't be made fair unless people have more than 10 points of Obligation each. If you have 4 players with 10 points of Obligation or less, you won't even have a double point for each player. At most you would only have doubles on 11, 22 and 33 so that means only 3 possibilities out of 4 players.
I brought t up and was asked to see what people here are doing. How do you fix that?
