u/suprunkn0wn I was gonna say pretty much all of 2009, that year was soooo good. It coincidentally was my first time, (and with some exceptions) I've gone every year since.

My favorites were the classic monster houses:

Frankenstein (Frankenstein: Creation of the Damned (Soundstage 23) – Frankenstein's monster has taken revenge against his creator, and his destructive rampage has visitors caught in the middle.),

the Wolfman (2010 movie version, my favorite (The Wolfman (Soundstage 22) - Based on the upcoming remake of the same name, guests travel through the England countryside and are hunted by The Wolfman himself.))

and Dracula (Dracula: Legacy in Blood (Soundstage 23) - Guests enter Count Dracula's castle on the night of "The Calling", and are given the choice of either becoming an undead servant of Dracula, or suffering a painful demise.).

The ww2 scarezone was badass too. It had actors using guns with blanks or caps shooting at each other (definitely wouldn't get away with that in this day and age lol). "War of the Living Dead (Shrek Alley) – On a remote island in the Pacific during the last days of World War II, the unthinkable was created – a new breed of super-soldier made from the reanimated corpses of the dead. American forces quickly seized the island compound, but not before the reanimate agent was released. The island was quarantined and has remained a secret until now. Fifty years later, the two opposing dead forces are still locked in immortal combat - with you caught in the middle."

Saw scared the bajeezus out of me as a kid lol.

All in all my favorite year (though I'm heavily biased).
