Our class played a crude kind of game like this for a marketing class once. You had to choose how much to spend each quarter. After one quarter I observed no declining marginal impact of hiring sales people, and a tiny, tiny boost in price from improving the product.

The next quarter my team released the shittiest product we could for the lowest price and spent 30x as much on salespeople as the next highest team.

We won by two orders of magnitude in terms of total net income. The next quarter, everyone tried to do the same thing to an even crazier extent, but there was a predetermined market size which we had already hit in Q2. So we scaled down drastically and everyone else ended up deep in the red paying spending X00 dollars in marketing to get a X0 gross margin on each customer.

In Q4 we were the only team that had enough money to field pretty much any salesmen so we did even better than Q2.

Greatly amusing.
