It's an upcoming game, published by Bethesda and made by Arkane. I thought the cinematic trailer was okay and looked kind of interesting. But then the gameplay trailer just grabbed me by the heart. Dang it, epic songs like that just get stuck in my head for months on end. I find the "feed him to the hungry rats for dinner" bit particularly inspiring. That was what got me into Skyrim in the first place - its music. If it wasn't for the awesomeness of the main theme, I'm not sure if I would have bought the game. But it isn't only that - the setting and art style, meant to resemble a painting, look so sweet. This interview (which doesn't allow embedding) with a couple of the creators talks a bit about their initial concepts for the game. Every mission is meant to be an open world in and of itself and over time, unlike in a solid open world like Skyrim, you return to the same areas to discover that things have changed. That...sounds like a definite step up. There's an emphasis on choice and experimentation too. The specific way you complete a mission changes what happens in the story, making for a more dynamic world. I am getting hyped, really, for the first time since seeing the Skyrim trailer. And yet, it seems like nobody's really heard about this game yet.
