So until dawn is pretty well done! The main reason I bought it is because the gf likes to play along (watch me play) games with a story line (batman, heavy rain, uncharted, etc).
I wouldn't have paid full price for it but it's entertaining. The reviews are spot on that it's a game that tips its hat to the cheesey teen horror flicks. Contrary to those movies though, I found the jumpy scenes in the game actually jumpy, because you're involved in the action. For example, using R3 reaching into a cupboard to grab a household item and some dammed Badger or something comes flying out at the screen. It's all cleverly done.
I recommend if you can pick it up cheap.
