I cant believe people are moaning so much about the Collars. I didnt find them a problem. Change your behaviour to play the game and stop expecting the game to adhere to your behaviour. Thats just Laziness. Adapt and Learn.

Very atmospheric, I felt the constant urge to strive forward to get out asap but was also drawn to the place enough to investigate it completely.
The Collar, Radios and Speakers. A new kind of enemy, a new challenge. Running into an area to escape Ghost people because of my low health and lack of provisions, only to suddenly hear beeping on my collar - Excellent stuff.
Hardsore mode was particularly fun to cope with especially at lvl 21.
Realising that every provision I pick up has a use instead of it being vendor trash.

Spoiler My biggest complaint is the Gap from exiting the vault area via the lift/elevator and suddenly appearing at the Fountain. It left a gap for me and I felt a lack of closure with the Christine character. After my Dialogue choices I was meant to go look for her, and she new this. Roleplaying my character I would have not have left the sierra Madre until I found some evidence of what happened to her. And I did spend a good hour looking.....then very sadly went to the wiki to find you cant find her. Christines Ending monologue does not justify this gap in anyway. Even a note at the top of the elevator or at the fountain would have been more plausible and would have let me LET GO. :shrug:
More references and dialogue from companions after I returned to the Mohave. I felt like I had a story to tell, talk about.
