Can a rules lawyer's level of experience actually be changed or defined by a game system or edition? Is it not instead a virtue of the player himself/herself?
A game system (of any edition) is a set of rules. A rules lawyer will always want to refer back to the rules any time his interpretation of the rules differs from another players/Dm's interpretation. Whether this is for casting magic missiles around corners, using the Force to kill a wookie, or the best way to beat up your superhero's arch nemisis, it all goes back to the game system for combat.
Any RPG (of this size) will have a complex set of rules, thus the liklihood of someone having differing interpretations will always be there. Therefore, if the rules lawyer ENJOYs his unintentional (or intentional) role as rules lawyer, then he will always enjoy rules lawyering in any edition.
Just my take any way.
