Major League Baseball asserts copyright ownership over everything to
do with the American and National Leagues that has not passed into the
public domain. For books that means almost anything since 1922. I have
no idea who owns rights to the Negro League data and to the data from
other countries. I don't know the rules for databases in any detail,
although I have heard of court cases declaring that facts cannot be
copyrighted, only their specific expression, and that not always. You
can buy the complete set of data for US baseball, going back about 150
years, on a CD-ROM.
has commercial products for seven sports, at $70 or so.
We would also need soccer and cricket, at least, which this US company
does not offer, and no doubt other sports and games. The Elo
international chess rating system is a major work. It has spun off
systems for many other tournament games. I have no idea who owns what
internationally, given the vast interlocking structure of
international governing bodies, leagues, and tournaments.

It should still work for teaching many CS topics.
Have you ever looked at Befunge, a 2D programming language with a
mobile instruction pointer and instructions for changing its
direction? It has been described as "a cross between FORTH and
