If you have the capability of Stern, it doesn't. You can crank out as many and then make LE editions to sell at a premium. Pros they sell as long as they possibly can make money from them.
If you're Spooky, your production line can only produce x games per year. Limiting the number just means you get to move onto something else eventually.
Licences also run out with time. So, if you know you can only make x games before your license expires due to manufacturing bottlenecks, then there ya go.
