Check out my game DR4X :D Its a fast paced, and simple 4x game where you can finish a whole game in less than an hour. You can also fully customize the setting of your game, down to like, the types of monsters and bandits and random events and tilesets, etc. https://store.steampowered.com/app/1704830/DR4X/

Its also only 5 bucks (it's on sale for the steam strategy fest)!
