Ten different eras here, each with their own distinct characteristics and history! Play all of them if you like or just choose your favorites.
Those great 1950s Yankee and Dodger teams can rarely win in a traditional league; they get shutdown by deadball pitching, and there are few superstar pitchers from the era. But in this league - they'll be playing each other! Can you drag the '53 Dodgers to the title they probably should have won? Were the 54 Indians an all-time great team or was their upset by the Giants proof that they were a fluke? Which Giants team was best - 1951, 1954, or 1962? That's 3 very different versions of Willie Mays to choose from.
How about the 1930s? Those great teams have the same problem as the 50s and just can't compete in most leagues, but here we can ask who was better: the Ruth-Gehrig Yankees, the Foxx-Simmons-Grove A's, the Greenberg-Gehringer-Cochrane Tigers, or the Dickey-Dimaggio-Gomez Yankees? The Dizzy Dean-Cardinals or the Carl Hubbell-Giants?
The 1976-87 era saw some of the greatest parity in baseball history (interestingly, at a time when many pundits predicted free agency would lead to exactly the opposite). Seven different AL teams, and seven different NL teams made the World Series during those 12 seasons (and every team except the Indians, Rangers, and Mariners won the division at least once during that era).
