I hate walking up to a place titled something like "Bob's Shack" and there not actually being a Bob there. How in the hell does my character know there was once a dude named Bob here? If anything, it just makes me feel even more that the game got pushed out WAAAAY ahead of time, because it suggests there was supposed to be some sort of content there.
The one that really got me was walking up to Cannibal Johnson's Cave, wondering who Cannibal Johnson was, MEETING Cannibal Johnson, and then ASKING him if he was really a cannibal. Was there a sign I missed? Nothing in the dialog indicated I'd ever heard of the guy before, and if he mistakes a guest for the Grim Reaper, I imagine he doesn't get out much...
Also, to the OP: Of course this got moved to spoilers. It details what you find at a number of specific locations that need to be discovered by players. That's spoilery.
And finally, on topic: I use Novac because of the benches, campfire, merchants, caravan players, water, and nearby campfire. (There is one even closer than the one near the Gibson shack, up near a cave to the right of the road leading to the Repconn test site, beside an old electrical tower.) I may start using Goodsprings again, though, as there are outdoor beds, Chet sells throwing knives, there are still benches, and the water is not irradiated. When I am on the strip and don't feel like fast traveling away to store things, I either drop it in the Drop Box to Novac or stick it in the Tops Suite, which I like using better than the Lucky 38.
