Try googling "surreal numbers".  It's an entirely new number system by
mathematician John Conway (creater of the game of life) and is quite intresting.
 It was developed specificly to analyze games, I believe he used it to analyze
the game of go.  The entire theory is based on only two axioms:

First axiom: Every number corresponds to two sets of previously created numbers,
such that no member of the left set is greater than or equal to any member of
the right set

Second axiom: One number is less than or equal to another number if and only if
no member of the first number's left set is greater than or equal to the second
number, and no member of the second number's right set is less than or equal to
the first number'.
