Last day for the Alan Wake Steam sale. Jump on it all DLC and the full game for $4. Should I buy it?

[S.T.A.G.E.]

Since I gave up my Xbox 360 and got a pretty good AMD run latop I thought I would pick it up. Its the last day for the Steam Sale, so what do you guys think? Should I buy it? Im a big silent hill fan but I hope this game isnt repetitive. It's one of the 360 "exclusives" that always eluded my memory.
