Well, gmo, you already hit the big one with stolen bases = extra bases. I know that the definitions for sacrifice hits and flies changed a lot in the early days of baseball, but the one rule change I remember specifically is that back in Babe Ruth's day, balls hit out of the park were foul if they landed foul, regardless if they were fair when they left play. As I recall, Baseball Weekly did a story on it a while back and figured that the Babe lost 20-30 taters to that rule... yet I don't expect OOTP to eliminate the "hooking, hooking" plays when it's 1935 or earlier.
