Graveyard Keeper

There's a ton of things to do, it has a wicked sense of humor, beautiful pixel graphics, a decent story and an amazing soundtrack. It's also much more involved than it looks. There are seven different tech trees and some really interesting logistical mechanisms that work very well together. All in all it's a well thought out and engaging little masterpiece that doesn't hold your hand, has an amazing free dlc with the game and no microtransactions or any of that nonsense. Highly recommended.
