Crowd attendance stuff...
Just as weather, time and other varibles can be set random, I would also like the crowds to have a random function - dead easy to implement.
I've noticed when playing Cup tournaments, that 1st round matches have few spectators, and increases as the Cup progresses. This is not a scientific study, just an observation.
Master League: I would like crowd attendance to be a separate part of a clubs weekly earnings, so a sold out stadium will give more points and show up on the balance sheet.
At the same time, the clubs performance during the season should also reflect on attendance:
A massive loosing streak, and only the die-hard fans remain on the stands.
A relegation/promotion playoff game, and the stadium is packed.
Buying high profile players should also boost attendance.
