Misread. >_<
Anyway, yeah I have no idea why we can't go back to it.
I mean, we could find our way back to the Mojave with no problem, but going back is?
Going back should be easier if anything!
The place is covered with a red cloud and a radio transmission.
If we can't go back, fine, but at least give me a damn reason for not being able to.
It's The Pitt all over again, I want to go back there simply for the sake of running around with the ghosts but can't...
On the other hand, if you mean Sierra Madre the casino then no, the place kinda falls apart after we leave it.
But I'd love being able to go back to The Villa to get the rest of the collectibles I missed and shoot random ghosts.
