No, it's not! Alan Wake was a great game but the only similarity between the two is the use of light to harm creatures of the night. We picked light because we didn't want to use guns or traditional "weapons", and it seemed logical when facing creatures that only come out at night. We've seen a lot of stories that use light as a form of weapon, including Don't Be Afraid of The Dark, Wes Craven's They, I Am Legend, and a bunch of others. We hadn't realized that so many people would think the game looked like Alan Wake, as we feel the two experiences are extremely different. There's a link, but it's more conceptual than anything else.
