yes it does matter.
i pretty much know all the 1-1000 players reputations, so i instantly know who to trust or not and who is lame.
also, anyone with like2k or less ID is (more likely) mature, because they could buy the game within that first hyped 2 weeks or however long the game was first new.
children cant do that, people with the money and means can. thats a major part of maturity.
