Of course, the problem for earlier years is that OOTP limits you to the same number of minor league teams at each level as there are major league teams. For the 16 MLB team era, for example, there were in fact 24 AAA level teams (though not all of them were affiliated with a major league team); OOTP would limit you to 16.
Then of course there were the additional levels of minor league ball, such as B, C, and D class leagues prior to 1963. Interestingly, the class of a minor league was determined by the aggregate population of all its member cities, and not by any intrinsic evaluation of its talent level (though in practice this is how it ended up working).
The only thing I'm doing is compiling the minor league schedules for the (likely distant) day when OOTP will be able to run with its minor leagues with their own separate schedules, league alignments, and playoff scenarios. The documentation of the schedules of the AAA level of the minors is progressing well, though I'm missing most of the post-1977 PCL and AA schedules...
