I've added 3 matches from my Career Mode to YouTube, see my channel https://www.youtube.com/user/crabshank3/videos
This one's tough
This one's spectacular.
This one shows the importance of tactics, and it has a yellow card in it :o
Using Aranaktu's cheat table, a proper PES style 'Coach Mode' is possible in FIFA 19 and with my MatchIntensity mod I expect good gameplay. I'll be sure to post at least one video soon.
I found the names that are in the database in static memory address, in SQL. Because I can't edit the db at the moment I tried replacing these all and it seems to work.
So, no matter the score the MatchIntensity will be the same. If you wanted to change values depending on the score you'd need...
If you're destroying the opposition, you will keep destroying them because the CPU don't change their tactics at all during the match except maybe right at the end. It's the same as FIFA 15.
The following ups the MatchIntensity to 3 in all periods of the in the game, this (if not placebo, pretty sure it's not) makes both teams' attacks more clinical and removes 'momentum' from the game so players are equally likely to score at all points of the match.
UPDATE 29/09/2018:
Now...
I think a way to do this is: when you Lock to Player in Career Mode, you control all the tactics and everything so you'd need to find a way to make the locked player actually controlled by the CPU.
Also if you sub that player off then it makes you control all the players. This whole process...
