Paradox Interactive not only makes games for nerds, it also codenames them after Kevin Costner films.
The strategy game maker's latest title is War of the Roses, which was a civil war over the throne of England. It's also a Michael Douglas movie. But this game isn't based on that.
Have a look at the trailer. For the Kevin Costner dorks out there (I know you are!), this game was apparently codenamed "Project Postman".
