Financial Exploit

injury log · 05-28-2007, 04:32 PM

In an MLB-style modern day fictional universe:

Just for fun, I decided to set my ticket price at $1,000,000. My market was 'tiny' and fan interest 87/100. Two strange things happened:

-My first game attendance was 4,000, which seems, well, just a bit high;

-after my first game, my gate revenue was reported as *negative* 2 billion dollars. I'm sure the numbers involved were too big for whatever bit representation the software uses for gate revenue, but it was strange to see a negative number for a figure that can't possibly be negative. It seemed to reset to zero after simming forward one day.

I lowered the price to $50,000 per game after the first, to avoid this negative gate revenue aliasing, and continued to average 4,000 people per. Must be a high income neighbourhood. In any case, it was fun to see revenue in the billions two weeks into the season! Obviously it's a minor bug that can be addressed via house rules, but I thought it worth mentioning.

Thanks for reporting this. Could you please let us know which version of the game you were using?

Apologies- I'm using the latest patch.

Injury_log,

All the revenue fields in the game are 32 bit signed integers thus allowing a maximum value of 2,147,483,647. This means that as soon as you reach that amount it will flip over to -2,147,483,648.

Fair enough. Ideally, the game would cap your ticket price at something reasonable, then.

Thanks for the explanation, redsoxford- the odd behaviour makes sense now.

And thanks, Nutlaw, for the quick reply and TT. Preferable to a ticket cap would be a corrected attendance/ticket price curve that works for extreme values. It appears that I'm guaranteed to sell at least 8-10% of my seats (at least when my fan interest is around 85/100) regardless of price, which means the model breaks down for ticket prices over about 10 to 12 times the average ticket price; revenue at these prices is guaranteed to exceed revenue at average price, and climbs linearly to infinity as you increase prices beyond that point.
