Game rooms are typically loud, there's way too much to take in, the DDR machine is always taken over by the crazy hardcore experts, and you suddenly find yourself all out of quarters after so many hours.
Theaters have soft, comfy chairs, are well air-conditioned (sometimes too well), offer a selection of yummy but ridiculously overpriced food, and everyone gets to enjoy the show together - especially a show that features tickling!
Both have their pros and cons, but if given a choice, Captain Jean-Luc Picard would much rather go to a theater.
I think that's what Numbah-1 is trying to get at.
