let's put down some maths, shall we?
both options cost you time and money exactly the same. suppose by upgrading seats you get 2000 new attendance each time and by upgrading stadium you get 8000. now let's suppose your ticket price is $10. now if you upgrade stadium you need 16 days and upgrading seats will be 5, 4, 4, and 3 days
if you have 1 home game per day then your table will go like this
Code:
day | upgrading stadium | upgrading seats |
0-4 | $0 | $0 |
5-8 | $0 | $20,000 |
9-12 | $0 | $40,000 |
13-15 | $0 | $60,000 |
total additional income difference in the process : $420,000
not to mention that you can also control your timing on another building exactly like fmldotcom said. this is perfectly a better option for me
