IGN recently visited Remedy's headquarters in Finland to discuss the successes and failures of 
Alan Wake.  According to Remedy's Matias Myllyrine, the team is very happy with the  "mood and the story and the setting" of the game. While the project  underwent significant changes during development -- it was originally an  open world game, for example -- Myllyrine believes it remains "very  close" to the original vision "in terms of feel, mood and atmosphere."
As for failure, Myllyrine wished that 
Alan Wake's marketing  would have had "an even crisper communication of what the game does,"  adding that it could have used "stronger advertising about what's unique  about this game." We'd certainly agree that a sequel -- 
should it see the light of day -- needs stronger marketing, but we have another piece of advice as well: Don't release your game 
on the same day as 
Red Dead Redemption.
