Kingdom on the Steam store. If you watch Mr. Fruit, he recently did a series on the game. For $9:50 CN (so like $8 USD ((thanksgiving sale))) you get a game that is pixelated and cartoony, but in a very realistic and HD way. There are always new things to learn about the game since you barely get any help on how to play other than complete basics (movement and placing coins) so it keeps you playing. Plus, it's just awesome. Go play it.
