A game mixing Hitman and Hatred, where you are a regular person with limited resources and skills, that starts assassinations on CEOs and vanishing. Start from the ground up, and manage to eventually kill the richest guy in the planet. The first CEO is easy, has no bodyguards or security, but things start escalating. Maybe include something like the nemesis system so CEOs security adapts to your style. You need to get more creative, but at the same time, you gain people support and you receive donations trough crypto, so you can spend it on the silk road to upgrade your resources and plan the hits. It's like a heist simulator. Start with a ghost gun, end up blowing private jets up, make the rich go hide in a bunker like Saddam Hussein. That sounds freaking fun.
