I also read the above statement years ago but the number given was something
more reasonable like 10^127 for possible number of games.  But I also believe
some assumptions had to be made about the games.  I also think the number of
atoms in the known universe is only about 10^78 or something like that.  All
this from my failing memory so maybe someone can give the correct figures.
