Yeah...somehow, this one does and does not surprise me at the same time. While it isn't out yet, there is apparently a demo and a steam wishlist possibility for Tank Mechanic Simulator. Just as the Car Mechanic version, you get access to a fairly decrepit vehicle, restore it, get it all running, and then either sell it or place it in your own collection.

It's just that it's a tank. Yep, you too can now pick apart, repair, reassemble and restore large angry houses with guns.
