The only mod I'd be ready to pay for is for a stadium I was waiting to see since I was a kid.
Now in Polish Ekstraklasa, almost all 18 teams have a stadium made either for FIFA 14 or 16.
Except one - Radomiak Radom. Entirely new venue was opened in September 2023, after 7 years of construction.
Stadion Miejski w Radomiu
Still not entirely finished, there are 2 tribunes instead of 4, but still capable of accomodation of 8,500 people.
I was on the opening, have a recording and some photos taken myself from the southern tribune.
If anyone would like to accept such a request, for free or for money, you can write to me in DM.
