A lot of the atmosphere of the original is stripped away with the anniversary graphics. However, I give the developers props for allowing you to switch to the old graphics on the fly.
The campaign has some fun gameplay segments but the story and boss fights are piss poor. The multiplayer has grown on me and I think it's pretty good now, but the loot boxes suck.
More pulpy than moody, American Nightmare never stuck with me like Alan Wake did. I'll replay the main game many times but I've been able to get through American Nightmare more than once.
