League games:
Full ticket money for the home team
You play everyone twice, once home and once away


Friendly games:
You split the ticket money 50/50
You have lower attendance at friendlies, how low depends on league and position (I think ) but usually around 7-10 at the start of a season and 10-14 in the end. A capacity around 13k is desired for friendly games, given that you only get VIP and executive seats.


Regional Cup games:
You split the money 50/50
The team with the bigger stadium when the match is scheduled will play at home.


What do you mean with the limit on max seats question?
