Im assuming fans is simular to how many people come to your homegame?
Otherwise people could just token the stadium up to crazy levels for their managerlevel and earn alot of cash.
End of last season i had 2.5k/3k on my homegames. New season and parking upgraded its now been max of 3k for awhile.
Do i dare to upgrade arena to next level at 7k right away or should i just make a few more seats at the time?
