That's an odd requirement for a boardgame.
It's a mystery solving game. There are five cases to solve but you have a limited amount of actions to solve the cases. The cases are all fictional but there is a backdrop of actual real world history and events which you might have to google or check wikipedia pages (or any page you wish really) to find the missing piece of the puzzle. It's very interesting, and the cases are all linked to form a greater story about secrets and corruption which my group and I are slowly unearthing. I am up to case four and think it's a great game, you just need a tablet, computer or smartphone while you play. We play with three players but it is easily done with two.
