So i decided to start a dynasty (Which will probably fail like the others

), which will ask this question: What if every league was a baseball league?
Now many of you have probably done this or something similar before, so i will do one thing to differ mine from the rest: the leagues will be split in two groups: an Outdoor Group, which includes Major League Baseball and The National Football League, will play in the Summer, and an Indoor Group, which includes the National Hockey League and National Basketball Association. I will also include a few foreign leagues for each sport. A list of chosen foreign leagues will be posted soon. Each league (Except Major League Baseball) at the start, will include "Filler Teams", which will be defunct franchises in the respective leagues history. In my universe there are certain rules to structure depending on the league:
For the Outdoor Leagues, a minimum of 8 teams must be kept.
For the Indoor Leagues, a minimum of 6 teams must be kept.
The game will start in 1901 with only Major League Baseball, i will report yearly until 1917, when the NHL starts, then i will report seasonly until 1920, when the NFL starts, then i will report monthly.
Oh yeah, and any other major league that started but folded later (FL, ABA, AFL, WHA etc.) will be included.
