I think newcomers should learn that the wasteland is a dangerous place. Then, they would learn the value of life and items they have. Just my two cents.
Well, the problem in Drakonis' idea is, that player will be forced to visit NCR through quest, and that will make him think that NCR is the "starter city" which is wrong. NCR isn't very safe In my opinion the vault should be CLOSED! The people inside shouldn't know anything about the wasteland, except these few(NPCs with their story) who came from outside to live in the vault and now are teaching you by giving you quests. In one moment, some bad things are going to happen in the vault and you will be forced to leave it - look at Fallout 1 and 3.Yes, there should be a way to gather resources so new players can learn how to craft stuff - but that should be some collapsed tunnel reachable from the vault or anything. Same with hunting.The idea is that a new player doesn't know details about cities on wasteland, but when getting out of vault, someone should mark a few of them on the map, though there will be nothing like you visiting NCR before you got out of the Vault - that would discriminate other cities.Dunno, well, not really, as I presented my vision there would be an option without tutorial.Start as a vault citizen(+outcast)/tribal(+outcast)/someone with a memory loss.
I am not sure how keeping players in a vault is a good idea; I think it will actually demotivate new players. For example you are a new player and you accumulate items and caps and then finally on reaching level 5 or what not, you exit the vault, and because of your virginity to the wasteland you run into an unprotected town (you probably would not know about town preview since you stayed in the vault), and rage quit because everything you worked for is lost. Right now, for new players death doesn't mean much, because they don't lose anything on their deaths.
Of course they'll be disappointed the first time they die. But this time, they'll know enough about the game world and be high enough level to get back on their feet.
I disagree, the most evident problems for a new player (at least it was for me), were:
