Here is what I can think of in terms of how it might actually work in the game based on the suggestion:Natural resource firms to be cheaper to set up and much bigger reserves, but operate more on basis of leasing and contracts where you pay the site owner a fixed amount each month/a set amount for each quantity of the resource you extract - it isn't be realistic to set up a mine you know is only going to operate for 2 years.
Natural resource firms:
-You buy the natural resources for X amount of natural resources only. The actual total deposit is larger than X amount actually, maybe 5-10 times as much.
-When the amount you bought /leased has been used up. You can renew the lease/buy new quantity. Your mine will stop operation until you renew the lease.
-If you do not renew the lease after it has expired for one year, your firm will be closed down automatically and you will lose all the business units there.
Make this a new option on new game setup menu, instead of replacing the existing mechanism.
