Managing a football club successfully requires understanding how the underlying database handles leagues, player registrations, and nation rules. When you launch a new save in Football Manager 2023, the scope of your career depends entirely on how you configure the database structure, choose playable tiers, and handle custom community add-ons.
The default database shipped by Sports Interactive includes over 50 nations and hundreds of individual divisions, but it doesn't unlock every lower tier or obscure football association out of the box. Knowing how to manipulate database sizes, configure advanced nation setups, and install custom expansion packs allows you to tailor your career path without ruining your computer's processing speed.
Default vs. Expanded Database Options
When starting a new game, the database size prompt dictates how many players load into your game world regardless of which leagues you make playable. You can choose between Small, Medium, Large, or Advanced setups.
- Small Database: Loads roughly 6,000 to 8,000 players globally. This option works best if you have an older processor or want lightning-fast simulation speeds, though it limits the pool of available free agents and wonderkids.
- Medium/Large Database: Expands the player count to 15,000–30,000+ active players. This setup populates top-flight and second-tier teams across unplayable nations with real players rather than grey-filled generic versions.
- Advanced Setup: Gives you granular control. You can load every player from specific continents, nationalities, or top clubs, letting you build a customized web of scouting networks without rendering your simulation sluggish.
If you prefer managing lower-tier or obscure teams, setting the database size to large isn't enough; you must explicitly check whether those lower divisions are loaded as "Playable" or "View-Only". Playable leagues simulate full match engines and league tables, whereas view-only leagues keep teams active in the background without letting you manage them directly.
How Playable Leagues Impact Game Speed
Every playable league you add to your save file increases the processing load on your CPU during matchday simulations and the nightly save cycle. If you select twenty different nations down to the lowest regional tiers, expect your loading times between days to stretch significantly.
To strike a balance, consider a phased setup approach. If you plan on starting a journeyman career in League Two of England, you don't need the top divisions of Brazil, Argentina, South Korea, and Australia running simultaneously on full detail from day one. You can add or remove playable leagues at the start of subsequent seasons using the in-game database modification options, provided your initial custom editor data files allow it.

Installing and Managing Custom League Databases
The default game structure leaves out many regional leagues, amateur tiers, and alternative national pyramids. Community creators bridge this gap by building custom editor data files using the pre-game editor.
Popular community projects like the FM Scout Database Downloads or specialized packs from platforms like Passion4FM unlock hundreds of extra divisions, ranging from lower-tier English non-league pyramids to fully simulated African and Asian domestic structures.
Step-by-Step Installation Process
- Download the compressed
.fmfor.ltcdatabase file from a trusted community hub. - Extract the file using standard archiving software like 7-Zip or WinRAR.
- Move the extracted file into your documents directory:
Documents/Sports Interactive/Football Manager 2023/editor data/. Create theeditor datafolder if it doesn't already exist. - Launch Football Manager 2023, start a new career game, and ensure the database version box displays your added files as active.
- Head into advanced setup to verify that the newly unlocked tiers appear under their respective country selections.
Common Mistakes When Configuring Custom Databases
Setting up a complex database incorrectly can break fixture schedules, cause game crashes, or result in broken promotion and relegation loops. Avoid these frequent missteps:
- Running Conflicting Files: Placing two different files that alter the exact same league structure (such as two competing English lower-league packs) will cause validation errors. Always read creator instructions carefully.
- Ignoring Game Version Compatibility: Major patches issued by Sports Interactive (such as the winter data updates) can break custom editor files built for earlier patches. Match your database file version to your game version.
- Overloading Lower Tiers with Foreign Player Limits: Adding obscure leagues without checking squad registration rules can trap your AI-managed clubs in infinite loops where they cannot legally register enough homegrown players.
Frequently Asked Questions
What is the difference between a playable league and a view-only league?
Playable leagues fully simulate matches, transfers, and table standings with active management capability. View-only leagues simulate match results and league tables in the background, keeping teams populated with real players without letting you take control of a club inside them.
Will custom database files affect my existing saved games?
No. Pre-game editor files and custom databases must be selected when you click "Start New Game". You cannot inject new league structures or major pyramid changes into an ongoing career save.
How do I fix greyed-out players in unplayable nations?
If you want real players to appear in nations where you haven't loaded playable leagues, go to the advanced database setup screen and configure advanced region or continent rules to load all players based in those specific areas.
Do custom databases slow down simulation speed?
Yes. Any custom file that adds active teams, fixtures, and player contracts increases the workload on your CPU during save processing. Keep your playable count lean if you want fast season progression.
