The setup rules for Scythe say:
Faction Selection:
Randomly shuffle the the Faction Mats and Player Mats, then deal 1 of each to each player.
Starting Player:
The player with the lowest number in the label on their Player Mat will go first. Play proceeds clockwise from there.
Designer's note:
The higher-numbered Player Mats offer slightly more lucrative starting track positions than the others, as those players are more likely to have 1 fewer turn by the end of the game than the player who goes first.
The question here is - when setting up the game - say I'm playing with three people - should I just randomly assign the three lowest ranked player mats, or I randomly assign three of total five?
The thing that I'm thinking about, is what say I randomly assign the 1,2 and 5 ranked player mats, if the person who has the five ranked player mat - has a larger advantage than if they'd been assigned the three ranked player mat.
