If I wanted to create a game with a CD chance to be lower, and there was an option on the New Game creation that allowed me to create a game for 5

where only players with a total of, say, 300 [Total Points] -- On hand + In play -- could join. This would not solve the problem?
I'm sure the 80/20 rule can be applied to CD's where most of them have equal to or less than 100 total points.
And while GR measure skill; there is a direct correlation between low reliability & GR I'm sure. Do you think people create GR games only for higher competition? No. They know the player will show up and play.
