take the number who actually is in the game, and don't reducing it further - maybe you end up with 60k whih would be ok too - and don't forget with that prices it takes several season to get the money back.
No, that would be far from ok. The teams that started the game early on and had all the huge cash flows are the ones that had enough money to build 30k+ arena's.
The game is different now and it's much harder to make money. Letting things go as they were would have meant that those that had managed to build huge stadiums with early season money would be engrained as untouchable to teams that started just 3-4 seasons later, let alone those that are starting now.
