It's very difficult to say who actually created the playing rules. Abner Doubleday is usually credited with creating the basic rules of the game. As the game progressed, many rules have been changed or added by commissioners or requested by umpires or other officials. Even today rules still get changed or added (the instant replay for home runs).
There is a high possibility that Baseball was derived from a much older British game called Rounders.
To have the rules written down means that when there is an disagreement the rules can be used to solve the problem. Imagine playing a baseball game without rules.
You are NOT supposed to be role-playing in Facebook,as it is against their rules.
BaseBall is always the same no matter where BUT some people like to make there own rules when they are playing but not in real teams and sometimes when people are just playing for fun they make it so EVERYONE is included.
