Strat-O-Matic is putting out a 108-card set of Negro League greats, based on their best five seasons. And it’s our friend Scott Simkus who’s acting as the principal consultant (see his work on the 1909 Cuban Stars here). Getting Negro League and Latin American baseball into tabletop games and text sims based on actual statistics is a great development, as far as I am concerned.
The leader in this so far has been Replay Games, which put together a yearbook and card set for the 1923 Negro National League based on Patrick Rock’s research (unfortunately, it seems, out of stock at the moment). I believe Patrick is also working on the 1923 ECL, which I’m looking forward to.
And I don’t remember if I’ve linked to this before, but Mischa Gelman has done the 1906/07 Cuban League (based on my compilation) for the free, open-source Strategic Baseball Simulator. Check around the discussion board; they have a huge variety of interesting leagues and seasons available.
