No radio to keep you company, no characters to really talk to, nothing in particular to do, just you and the peculiar rock paintings of the tribals. Oh yeah, and the unresponsive Dead Horses aimlessly crouch walking around the river alone. I was messing around in one of the caves once, I SWEAR I saw a bright figure just walking around one of the Survivalist's forts.
For those of you who read the FO3 number station creepypasta about the Numbers Station with Three-Dog, there is a huge potential for creepypasta with Zion. Like, with the UHF signal that gets stuck in your radio after Dead Money (and is unresponsive afterwards) actually activates in parts of Zion, and then it has X person saying creepy thing Y, etc.
Anybody else notice the almost excessive creepiness of post-DLC Zion?
