The big change to the mechanic of the Original would be getting "points" based on being a good townie (providing cases, voting, FoSes, posting meaningful posts etc.), and once you get a certain amount of points, you would "rank up", like in the game, and aqquire anew PR, or a fix to an old one. All people would start at Rank 0.
EX.
I am at rank 0 (and I start of as a Vanilla Goon)
When I rank up, at say, page 5, I may gain a GF ability, but only with a 50% chance of working (rank 1)
When I rank up again, at say, page 12, My GF ability will always work (rank 2)
For the last rank up, I may get a 1-shot Janitor ability (hiding the role of the other player, but revealing it to only that player)
Now, you may be saying
