Milkstone Studios has made an excellent game engine built upon the XNA Framework and their work is amazing. Contrary to many Xbox Live Indie Game Critics, their games are fun, they look professional, and you can tell that they put a lot of effort and work into their creations. Its not easy to make an indie game or a game engine from scratch using XNA. I hope the gaming community recognizes their hard work and find their games fun to play as much as I do. This engine deserves a 10/10!
