Glad some people enjoyed it, as I said In my own post before I saw this It just felt lackluster. I like to either play the "blow em all to hell with vastly stupidly powerful guns" or "Silent Sniper" ... I didn't get to do much of either, I also didn't feel the forced companions were much help at all. While the VO's were funny to start, after 3rd time I was seriously tempted to "Silence" them.
Maybe my 3 was a bit harsh but I Just don't feel I got my $10 worth. For me, I LOVE crafting odd things, and collecting interesting guns. The tommy gun was fun for about... 1 clip, after that I preferred either the pistol or my sniper rifle.
I Loved the area though, and If I'd been able to bring even ONE companion of my choice it would of been a blast to explore again and again.
Also as Edouard said there's really no reason to go back to any location twice. The terminals provided either a laugh or an "eew" which I liked but weren't really used much besides three page diaries.
Oh I should also note I was extremely disappointed I couldn't find a single weapon mod anywhere. It wasn't till I left Zion and checked the gunrunners that I was able to find a slide, silencer and extended mag for the .45 auto.
