Take, for example, the Silver Rush energy weapons store. (very minor spoiler) It's supposed to be a heavily guarded place, right? Guys with guns everywhere, forcing you to hand over your weapons before going inside....(somewhat less minor spoiler. but still pretty minor) seeing someone "made an example of" by the store owner for not paying full amount....yet....
(no more spoilers here)
I was able to literally steal every single thing from that store like it was no big deal. First time around, I just popped on a stealth boy and snagged everything. I reloaded my save, though, because I realized I didn't even have to use stealth at all. You know that not-often-used button to carry stuff around in front of you (right stick button on 360 controller, not sure what the keyboard command is)? I used that to pick every item off the shelf individually, carry it into the bathroom, and duck down and pick it up there. None of the numerous and well-armed guards seemed to think that it was any cause for alarm that the only customer in the store was taking every single item into the bathroom and none of the items were coming out. These are the guards that constantly say "I'm watchin' you!" and other general threatening things that well-paid guards say. The stuff in that store alone is worth thousands of caps. Thouuuusandddssss. Oh, and also...I don't know if this is story related, but you don't lose any karma for stealing from this store.
And that, my friends, brings me to the next issue: karma! What the hell is with karma? I have been robbing people blind right in front of their eyes the entire game, and my overall karma is still "very good". Not that it matters, because karma doesn't seem to do anything at all ever.
Oh, also, I don't think I even have 25 sneak. I'm pretty much set for post-apocalyptic life cap-wise, almost entirely due to stealing, and I didn't have to invest a single point into sneak. It's hilarious how easy it is to be "hidden" and steal stuff. I'll be standing in front of someone, duck down, slowly creep around them while apparently hypnotizing them with my chants of "yooouu can't seeee meeeee," and proceed to steal all their [censored].
"Hey, would you be interested in buying these cartons of cigarettes that I've totally had this whole time and definitely didn't just pick up from behind you?"
"Why, sure! How could I possibly refuse such a great deal!"
yeah I guess that's all. I'm gonna go steal some more [censored].
