The movie theater consists of a reception area, a projection room, and a single theater with a movie screen. There are a bunch of Soda cans and Chips in there. Inside the theater itself are a large number of eggs, but there's some decent loot once they're dealt with. There may also be a Protocol Droid wandering around in the lobby.
While in the movie theater, make sure you look twice before using the Replicator. Some things never change, even in the future.
The casino contains slot machines, a bar, and a card table.
Sensual Stimulation Chambers
~ Rosenberg, 08.JUL.14, RE: My nanites
A form of adult virtual reality entertainment, the Sensual Stimulation Chambers can also be found on the Recreation Deck. You'll find four locked rooms, each with a different "simulated stimulation partner." A replicator by the stairs will sell you keys to these rooms (at exorbitant rates). In order to keep the rating of this game within reasonable bounds, all equipment inside the rooms is broken.
There's a rather large stock of Nanites (Supposedly Rosenberg's Nanites), and some Cyber Modules, in Nikki's room in the Recreation Deck's Sensual Stimulation Chambers.
