2. Build as much as you can as fast as you can.
Agree, as long as you have nothing better to do with your money, which is highly improbable. All those empty seats represent money that isn't working for you this week ... or next week ... or the rest of this season ... or next season ... or the season after that ... see the pattern there? Do you really have nothing better to do with your money for that long?
On the other hand, those seats you
don't build yet are earning you nothing this week, or next week, etc. The important thing is to try to make sure you can find as much money as possible to invest in the arena while still being competitive, and that's usually easier when you first start out.
