Update 16.09.26
1. There was a major bug of youth competitions not being played/wrongly played across the majority of all nations. This is now fixed
2. added some more history data
3. The available leagues in all nations ae currently close to be final. Please do not ask if I can add league xy or why xy isn't playable. It has its reasons:) I will see and evaluate if there are some lower leagues which would make sense from a balancing perspective.
4. when giving feedback, please load this specific save-game, so I can be sure that it's not down to an error on your side due to incompatible mods etc:
Save-game with all leagues playable

5. Please delete ALL previous files and add all files of the new download-link in the editor data folder again. (plus the sortitoutsi transfer file)

I hope that this is the final version for the BETA release on Friday:)
Download-link is updated

Update 14.09.26
1. France 4th division is now playable
2. Germany's 4th division is now playable
3. Fix for Belgian League system
4. Additional files available for a start in 2026 for Turkey, Wales
Delete ALL previous files and add all files of the new download-link in the editor data folder again.

Update 13.09.26
1. Fixed issue in France's 3rd and 4th division
2. World Cup 2026 has now it's correct history
How to install:
Delete ALL previous files and add all files of the new download-link in the editor data folder again. Some files have now names like "France v4", this is just for me to keep track which version is currently up.
3. additional informations:
- In Europe, not all leagues received a separate league file, for example Turkey. But their league history and everything else is up to date. The only consequence is, that there is no 2026 start date for those nations but you can simply select a start date from a different nation, for example england and still play in Turkey
- I had to manipulate the UEFA Coefficient a little because there is no way which lets me add the points for the season 25/26. It's calculated in a way, that everything will still correct despite showing "0" for all Nations for Season 25/26 until 2030/31. In this season, ratings may vary very slightly from real numbers for one season. after that, everything works correct again.

Update 12.09.26
1. There was a mistake on my end where I've put an old UEFA Fix file into the download folder instead of the current one. The old one contains bugs, the new one should work fine. Sorry about that. A new save is needed that it works fine. DELETE ALL FILES FIRST AND USE ALL FILES OF THE UPDATED DOWNLOAD-LINK
NOTE: There is a visual glitch where some teams are displayed to be playing in CL and EL (ex. Bournemouth). This is a visual glitch only
There seems to be an issue in France's division 3 and 4. I'll check that this evening for division 3. Division 4 is "view only" so it's not on my list as a priority
2. I've also fixed some histories where there were duplicate winners for season 25/26. This is a visual fix only and has no impact on gameplay
3. Just to be a bit more clear which transfer file you need to download from sortitoutsi's website:
1. Download the "Basic Data Update" in this link, the free version.
2. Only copy the following file in that download into your "editor data" folder: sortitoutsi.net FM26 Data Update - Contracts (2026 Start).fmf, NO OTHER FILE, ONLY THAT FILE https://sortitoutsi.net/football-manager-data-update/download/17?no_date=1
3. Increase Realism Megapack: All the files which are in the folder "01_Men's Football" must be copied and placed into the "editor data" folder aswell. That's it

Hi everyone!

My final update of the Increase Realism Megapack for FM26 focuses entirely on the 2026/27 season. This update goes well beyond the previous adjustments, bringing you an updated football world with revised leagues, international competitions, player ratings and many other improvements for your next long-term save.

🌍 Final FM26 Update – 2026/27 Content Overview

The in-game start date is summer 2026. Your save begins in the correct year for the 2026/27 season, with the updated leagues, competition histories, continental participants and other database changes aligned with that starting point for a realistic setup.

What has been updated?

Worldwide leagues

Leagues worldwide updated for the 2026/27 season, including competition structure and format changes.

Competition histories

Updated historical records, including previous competition winners, to match the new starting point.

National reputations

Reputation adjustments for all nations, aligned with the 2026/27 season.

Club reputations & finances

Club reputations and finances adjusted to reflect the 2026/27 season.

Continental competitions

Correct club participants in continental competitions across Europe, Asia, Africa, North and Central America and the Caribbean, South America, and Oceania.

World Cup fix

Prevents the World Cup from being played again in summer 2026.

Worldwide CA/PA adjustments

Revised current ability and potential ability ratings for players worldwide.

250+ newly created young talents

A total of 250+ newly created young talents included in the pack to better represent the next generation for the 2026/27 season.

Further database improvements

Numerous additional adjustments focused specifically on a more realistic2026/27 starting setup.

🤝 A special thank you to MasterIgor

The included league files are based on MasterIgor’s files and have been created and adapted for this update with his explicit permission.

His work forms the foundation of this part of the pack, so it is important to me to give him clear credit for his contribution. Thank you, Igor, for your permission, your trust and the extensive work you have allowed me to build upon!

🔍 My plans before the Public Release

1. Further analysis and bug fixes

With such a large number of files, there is always a possibility that I have made a mistake somewhere.

Over the next two weeks, I will therefore analyse the final data again using an XXL save that is already running. In particular, I will look at how the various changes work together and how the football world develops over the long term.

Evaluating the current version and fixing any issues will be my clear priority before the Public Release.

2. The XXL save is coming to Patreon

I will also upload the XXL save to Patreon in two versions: one at the very beginning of the save and another in a year far into the future.

This will allow you either to start with the updated setup or to explore for yourself how the football world has developed over a long period.

3. What changes for my “List of Files I recommend for FM26”?

Quite a lot, obviously :D

With the significantly expanded scope of the Megapack, you now essentially only need the free version of the sortitoutsi transfer file and the Real Name Fix alongside it.

Beyond those, no additional database files are generally needed.

Of course, this only applies to the database: you can – and should :P – continue using all your graphical mods, such as logos, player faces, kits and similar additions.

4. Possible additional lower-league files

I will try to create a few additional lower-league files, for example for Germany.

However, I cannot promise anything at this stage. My focus is firmly on evaluating and validating the current version. Additional league expansions will only be added if there is enough time available.

🔮 Looking ahead to FM27

MasterIgor has told me that he will be skipping FM27 and currently expects to return for FM28.

He has given me permission to continue his league project for FM27. I will do so to the best of my knowledge and ability, with the intention of handing the project back to him for FM28.

This is exactly what respect within the modding community means to me: communicating with each other, asking for permission, acknowledging other people’s work and treating it responsibly.

I wish this were standard practice everywhere. Unfortunately, that is not always the case, which makes me appreciate Igor’s trust and our collaboration even more.

📅 What is planned for October?

Just like last year, there will be no monthly update in October. Monthly updates will resume in November.

Instead, October will be dedicated to planning and preparing for what comes next.

I completely understand if you decide to pause your support for that month. Of course, I would be happy to welcome you back on board for FM27 ;)

I am equally grateful to everyone who continues supporting me throughout October. A month with less visible output, but important planning and preparation behind the scenes. That support means a lot to me and helps me dedicate the necessary time to these less visible parts of the work.

❤️ Thank you for your support!

With this final update, I am wrapping up the content additions to the Increase Realism Megapack for FM26. Until the Public Release, the focus will now be on the final analysis and any necessary fixes.

Whoever you are and wherever you come from: thank you for your support! <3

I hope you have enjoyed my work for FM26 and that this final update will bring you many more exciting saves:)

Cheers
David
