Making Football Manager more realistic is possible by installing a number of addons created by the community. And no, this is not about logopacks or facepacks.
Most of the addons featured below are custom data files that either tweak certain aspects of how the game works or add more depth to what's already there.
Certain addons are available as packs which include multiple files. And since these files are created by different people, there are some cases of files that do similar things, so you'd have to choose just one to avoid data conflicts.
I'll briefly explain what all the different files do, where to find them, and when you need to make a choice to avoid possible conflicts.
So, let's get to it.
