Couldn't tell you the expansion costs of each though. Except it costs $341M to construct the World Arena and $341M for the final full seating upgrade expansion of the World Arena.

WHAT THE F!@K???

I'm only just about to upgrade to the Small City in the next 5 days and that only costs £3.6m to do. It's going to cost £682m to actually finish the stadium upgrade fully.
