So, I was playing ps1 armored core recently and the gameplay is awfully rough to go back to, but one thing I had forgotten about was the mercenary side of the game. You accept missions based on how much they pay, the repairs for your mech are deducted from the pay and then you use the extra money to buy better weapons and whatnot from the shop.
I was really surprised how well this hook worked even though the gameplay itself wasn't that great. So, what are some other games with this type of thing. Not where the business simulation IS the game, but where it's used as something to make the game more interesting. Recent games that come to mind are Moonlighter and Battletech. Can you think of anyhting else?
