Demonarch

In active development since 2016, this is a first-person strategy game about summoning demons and herding them around like terrible cats to topple a civilization one castle at a time and finally become the new king, all on the orders of the guy who already did that and now spends his time making the people learn his tale. The game plays entirely in first-person as you re-live the Demonarch's story of conquest, which is why this game does not allow you to fight or build anything - he never did either, being too busy keeping demons happy and escorting them around. Demons don't take orders, of course, so your only way to lead a charge is by going in first. Your primary defense is the element of surprise - let news of your invasion escape and other towns will prepare. Let witnesses discover that YOU are the demon summoner and difficulty will increase everywhere that news reaches. Made by a single disabled Army veteran over 8 years and counting, plus 49,000+ Eyes of the Tiger by Survivor. Yes, this game is developed by that one crazy guy who listens to the same song on loop while creating this game.
