One Small Step Games is running a Kickstarter campaign for Holy Roman Empire (which makes OSSG sort of the Hapsburgs of the deal, I guess). Players are charge of one of the countries involved in the 30yrs War.

They're already rather close to passing their funding goal with still 28 days left on the clock.
