Give me some ideas

Water melon slicer game but after a while something happens and it becomes a full out game.

a game where you focus on stealing mail from people, stealing mail from certain homes give better prizes, there are 3 types of mail, artifacts (collectibles), packages (sold for good prices) and letters (sold for bad prices) you drive a van and you can customize that van to increase the chances of getting away with taking the mail, if youre cought your money is taken (not all of it) and you sell your mail from a homeless guy, hes homeless but still buys mail from you (dont ask why) and you can buy upgrades too.
