Welcome to Major Sim Baseball:
A New Chapter in Baseball History

In nineteen seventy-two, a bold vision took shape: to create a league that embraced both the tradition of baseball and a spirit of innovation—a league that was adaptable, dynamic, and truly competitive from coast to coast. This vision became Major Sim Baseball.



What is "NimBLe"?

Officially known as the National Baseball League (NBL) within Major Sim Baseball, the league earned its nickname—Nimble—due to its fast-paced, strategic gameplay and innovative approach to America’s pastime.
It’s more than a name; it’s the essence of how baseball is meant to be played. It’s about staying one step ahead, adjusting strategies on the fly, and creating a league where every inning matters.



The Structure: Four Pennant Races, One Goal

Major Sim Baseball is built on a commitment to the classic spirit of baseball competition.

In the early days of baseball, there were two pennant races, one for each league. As divisions were introduced, there were four distinct pennant races—a format that created more intense competition. However, with the later addition of the wildcard, the purity of these races was lost, leaving the world with no pennant races at all.



Major Sim Baseball aims to maintain the excitement
of these four true pennant races,
each with its own path to glory:

Eastern League of Sim Baseball Teams – Divided into North and South, each division boasts five competitive teams fighting for the right to compete in the League Championship Sim for a true pennant.

Western League of Sim Baseball Teams – With its own North and South divisions, the West carries its own rivalries and legends.

Every season, only the best from each division will advance, making every game count.



Intense Rivalries and Balanced Competition

In Major Sim Baseball, teams face their four division rivals twenty-three times each—ensuring that division crowns are truly earned. Meanwhile, they meet their league rivals from the other division fourteen times each, creating a balanced schedule that rewards regional dominance.



East vs. West: A Tale of Two Leagues

The East and the West operate as separate worlds—teams will only face off within their league, intensifying regional rivalries and building to epic clashes.
The only exceptions are the All-Star Game and the World Sim, where the best of the East meets the best of the West, creating the ultimate stage for baseball’s finest.



Historically Accurate, Uniquely Dynamic

With twenty teams compared to MLB’s twenty-four in 1972, Major Sim Baseball ensures a deeper, more competitive player pool. The league always maintains fewer teams than MLB, maximizing talent across rosters and keeping competition fierce. Each player is 100% scouted and rated with complete historical accuracy, while the OOTP Development Engine adds a layer of organic variance, making every season a truly unique experience. Player ratings are recalculated every three years, a choice that balances realism and fluidity in a way that dedicated fans will appreciate.



1972: A Historic Beginning

Major Sim Baseball stays true to history, starting without the Designated Hitter rule in nineteen seventy-two. As the years pass, rule changes will be introduced as they historically happened, maintaining a balance of realism and tradition. The inaugural All-Star Game will be hosted in Chicago, paying homage to the original MLB event and setting the stage for future seasons.



Expanding for the Future

Major Sim Baseball will grow to twenty-eight teams over time, with expansions planned for 1993 and 2002. In each expansion phase, four new teams will be added—one to each division—ensuring that the league remains balanced and competitive throughout its evolution.
