Guys, I am gonna leave this here and simply let you try it.
Pure Football Simulation 16 v1.0 download link
Have in mind some things. I am using this OVER
@chojanpineapple FIFA 16 mod. I think I am adding every single gameplay file in my gameplay, but maybe he changed something else I don't know about, so I highly recommend using aswell his mod as a base and apply mine over him, yet my mod should (and will) work alone. But as said, maybe he brings some more changes I don't know about so yeah, I still recommend his mod just in case.
About the mod itself. This is a collaboration between donnie and myself. He passed the attribdb files through an AI that suggested certain values to make the game feel more realistic. He passed that base to me, I polished some things I thought they could be better, added some things of my own, etc., and combined it with my cl.ini, product.ini and rna.ini to bring you this incredible gameplay. But without donnie's work over the attribdb gameplay, aside his work to bring us a FIFA 16/17 attribdb editor tool, none of this would be possible. This is why I ask you a big thanks to him. I have also something in mind to express him our gratitude, but will talk about it when it is time to.
Last, but not least. Installation instructions.
Step 1. Download Creation Manager 16 or any other tool that allows you to regenerate bh files.
Step 2. Extract files from the .rar and copy them into the root folder. This means "...\FIFA 16" folder, whatever the whole route to it is. Essentially, the folder where it is the exe file and the config file. This folder has a data folder inside it, so when you copy the mod files, it'll probably ask you to either combine folders or simply overwrite files. Say yes to all.
Step 3. Go to Creation Master 16, open it, go to file tab, and press over "open - select all" to ensure you can select which FIFA folder you're using. Select FIFA root folder, then select the files the program asks for to inititate the loading process, then, when it finishes, go to tool tab and select regenerate BH files

Step 4. (Optional) Select the number of minutes you want to play by editing the cl.ini. Find the lines
HALF_LENGTH=45
AI_SETTING_HALFLENGTH=45
at the beginning of the cl.ini, and change them to the number of minutes you want EACH HALF OF THE MATCH, to endure. Or just comment them with // if you want to select the duration of the match INGAME.
Step 5. Run the game.
Step 6. (Optional, but recommended) Set the games with the next options.

In Game Settings, the optimal difficulty is probably World Class. Beware though, cause one of the things I couldn't fix yet is AI being laser precise with crosses. So while the general difficulty of the game is kinda ok, even low in terms of defence, the freaking AI will be extremely precise with foul and corner kicks crosses, or simply normal crosses from the wing, and are very likely to end in goal. Too much likely to be remotely realistic. It's right now the only thing that really puts me off the matches (maybe alongside stamina use). The other important change here is
TO SET GAME SPEED ON FAST since it allows the characters to react much faster to the different events around them and makes animation much faster and consistent.
Set the camera, rules visual and audio you want, then go to user and cpu settings. You must put BOTH USER AND CPU SETTINGS as it follows. I'll include pics only of user settings cause I use same settings for user and cpu, but maybe you can balance CPU crossing accuracy by setting pass error a bit higher in CPU side. It's completely up to you though.
Ok, so some specifications about this. If you want a realistic speed and tempo, KEEP SPEED SPRINT TO 1. Don't push it further from there or you'll have unrealistic player speeds, and the game will be extremely fast. Also, you destroy the animation/sprint speed ratio if you put this up. I'll explain myself. One of the reasons that FIFA always feel so fast is because the sprint speed is so high and reaction so low that defenders can't almost react. What we are doing here to make the game tempo feel much more realistic withouth game feeling sluggish is upping the reaction and animation speed (by setting game speed to fast in the match settings tab) and lowering the sprint speed (aside from passing speed in the mod files itself) so that now, every run, every pass, every decision has to be taken much more carefuly cause defence reaction is much more on par with both sprinting and passing, so... more interceptions, more tackling possibilities, etc., and therefore, much more need of thinking carefully and a much more realistic tempo, cause thinking needs time and pause. Game is expected to be played with rythm changes and looking for fast, but easy transitions combined with difficult deep through balls, or contested crosses, like irl football plays.
Now, this being said. If you feel the lanes are extreme wide, you can reduce line width setting, if you want a more open football, then maybe reduce line length. If you want the line height to be lower, you can do so by setting it to a lower value. This is completely up to your taste and how you feel the game. I am rather giving you basic parameters to have the most simulative football possible, but everything is customizable to your tastes.
Last but not least, this game is recommended to play on fully manual setting, so go to your pad settings and set it as it follows.
And nothing else here to say, you're ready to play this marvelous sim. But before leaving you to play, I again want to give thanks to donnie for his fabulous work both on the tool and on the base of this gameplay files,
@chojanpineapple and doctor fidel + for making gameplay and graphic mods that I also use as a base or take things from them (cl.ini mostly), and every single person that has helped me to achieve this along the years of sharing me gameplay mods and such. I have done nothing but mashing several changes together that I found in all the gameplays I tried through the years and try to mix them so that they work properly.
That's everything on my part, try this mod and enjoy realistic football. I'm all ears to hear your feedback and try to improve the game further.
