Hey everyone,

Like many of you, I love FM and i didn't like fm26 tbh so i returned to fm24, but I’ve been getting really frustrated with the arcadey feel of the default Match Engine. I got tired of seeing laser-guided ping-pong passes and shots, defenders doing random suicidal slide tackles, and goalkeepers acting either like Prime Buffon or completely forgetting how to dive.

So, I decided to take matters into my own hands. I've spent the last few weeks digging deep into the ME files, running endless tests (simulating full seasons in Full Detail across different leagues like the Portuguese Primeira Liga and German 3. Liga), and comparing the in-game stats directly with real-life Opta data.

The goal wasn't just to make the game "harder"; I wanted to make it play like actual, real-life football.
 

What’s changed:

Ball Physics & Passing: The ball actually has "weight" to it now. Short passes aren't hit like powerful shots anymore, and long cross-field balls have a realistic, natural trajectory. Build-up play finally looks like real football.

Defending Behavior: Defenders are much smarter. They stay on their feet, jockey properly, and only commit to tackles when it makes sense. Say goodbye to those ridiculous, game-breaking red cards from mindless sliding tackles.

Goalkeepers: I've tweaked their reaction times and agility so they behave normally. They make the saves they should, but they won't pull off superhuman, teleporting dives every single time.

Direct Free Kicks: I found the sweet spot for this. Set-piece specialists can actually score now, but at a lower realistic rate. Top teams and specialists will get around 0-5 free-kick goals a season (exactly like real life), instead of 15.

The Results: I didn't just eyeball this. After running multiple full-season simulations, the match stats are virtually a 1:1 match with real-life league averages. Pass completion (around 82-84%), shots on target, foul counts, and set-piece goals are exactly where they should be for modern football.

If you enjoy winning 6-5 every weekend with 40 shots a game, this ME is definitely not for you. But if you want to feel like a real manager where your tactical tweaks matter, player attributes actually show on the pitch, and the game flows realistically, give this a try.

I want to give a massive shoutout to the guys in the modding community who have been digging into the ME files and sharing their findings and raw data freely. I didn't discover all these variables myself. I basically took their incredible groundwork and decided to go one step further using Gemini 3.1 Pro & ChatGPT 5.4.

I hope you enjoy it and i would love some feedback so we can improve it together. Btw i use it along with Daveincid realism pack.

Installation: Delete the simatch.fmf file in the instsallation folder (better make a backup of it) and replace it with the simatch folder i have in the download zip.
New save is not required.

I runned my final Simulation test and my new results were stunning. i am gonna give them to you so you can check what TrueSim has achieved.
Where i have put the R7, it means the reale top 7 europe leagues average number.
 

**** Direct freekick goals R7: 0,75 goals/team/season VS TrueSim_1.1: 0,77goals/team/season
**** Cross Success Rate R7: 16%-23% with an average 19% VS TrueSim_1.1: 18,8%
**** Goal ratio from Headers Ration R7: 16% VS TrueSim_1.1: 15,9%
**** Successfull Pass Percentage R7: 78%-90% with average 84,5% VS TrueSim_1.1: 85%
**** Shots per game R7 11-16,5 with an 13,5 average VS TrueSim_1.1: 10,5-17,2 with an 13,8 average
**** Shot conversion rate R7: 9%-15,6% VS TrueSim_1.1: 8,8%-15,4%
**** Fouls per game per team 11-13 R7 Vs TrueSim_1.1: 12,3 average
**** Yellow Cards per team per game average R7: 2,1-2,4 VS TrueSim_1.1: 1,8-2,6
**** Goals from corners R7: 5,5-7,5: VS TrueSim_1.1: 5,9 average (I could boost this a bit but because i know how corners could be exploited, i left it there)
**** Indirect Freek kicks goals R7: 3,5-4,5 per team per season VS TrueSim_1.1: 4,2 average

The version 1.1 will soon be uploaded and will not be modded any more till i get community's feedback.
Mac version will also be included for TrueSim_1.1.


Update 1.4:
Sacrificed a bit of delivered stats in order to Improved the match flow and motion feeling.
Now the game motion feels more natural and smooth, more attacking & beautifull football is being played.
To keep scoring realism up as much as i could, because FM24 overperforms in scoring, i had to pump the GKs just a bit.


Update 1.5
Fixed some visual bug headings occured after a cross has happened.
Fixed some really powerfull driven crosses that were impossible to defend.
Lower the effectiveness of gegenpress a bit, now being punished more if used when you shouldn't.

The version 1.5 will be the last till late May since i think only a lot of feedback can make me change things.
A txt with installation instructions is also placed inside the zip file.

For the optimal visual experience, it is recommended to play at +1 speed.
