So an idea I have to make the game more immersive is to have team talks take place in the dressing room from the perspective of the manager, you can look around and choose players to give individual talks to and you can judge the reaction of the players to your overall team talk through body language. Also, I think having the ability to see the game from the manager's perspective on the touchline would improve the realism, being able to watch the game from the dugout and get up and walk to your technical area would be a nice addition, this could also lead to interaction with other managers.
When I envision Football Manager games in 10-20 years, I see them going the way of a fully immersive VR managerial experience, I think this would be a huge step in that direction.
Still find the main problem with the match engine to be defenders in acres of space heading the ball straight to the opposition. Just happened to me in the 89th minute and we conceded a late equaliser
