I really enjoyed how much this DLC leaned into the oddity and comedy of Fallout, after Dead Money it made for a nice palette cleanser. There's so much interesting, funny dialogue to experience in Old World Blues that it makes up for the rather unremarkable setting. The Think Tank and other interior spaces dotted around the map provide plenty of lore and quests to chew on, but the exterior of the Big MT just isn't as cool as Zion Canyon. At least, not to me. Still better than navigating the Sierra Madre though.

That was one sexy light switch.
