I enjoyed it, it's worth playing it if only because the ambiance. The characters are pretty well written and it does discuss interesting topics. It's pretty simple ultimately (not good in my book) and, I don't know if it was my addled mind or the game's fault, the actual mystery didn't seem that well made (in the sense of the motivations of some characters or the ultimate showdown with the villain). I didn't find my ending particularly satisfying either.
Still, as I said, worth a play.

Genuinely the best Fallout New Vegas mod.
