I had this game idea some time ago.
- You go on a shopping spree (press a button). You buy everything on credit.
- Then you return to your castle, where you pile up your loot.
- The debt-collectors come and attacks your mansion. The amount and difficulty of the debt-collectors depends on your dept. To defend yourself you shoot your loot at them. More expensive loot (cars, trucks) are better then smaller loot (shoes, phablets etc.). When you shoot the debt-collectors they die.
- Then it's time for a new turn, start over!
The goal of the game is to balance debt, loot quality and the difficulty of the debt collectors. Thus - the more money you have the more ammo you have, but it also makes the game waves more difficult.
