Right. But before they start that reading, they don't know. They can't know, as they've never done it before. It isn't like people are born with this stuff in their heads, they either have to spontaneously generate the idea, or get it from someone, or some book.
So, why not have some of those books include some of this sort of information, for them to pick up? Why not make a whole book about it, so they can include it in what they pick and choose to use?
One thing I think it is good to learn - the experience of one person is probably not demonstrative of the universe at large. I'm happy you have never seen an uninspired new player. I, myself, have seen inspired new players who didn't have a good idea of what direction to take that inspiration. Some ideas of where one can go could be very useful to folks who haven't been around the block a few times.
And, even to those old hands you talk about - the folks who have gotten stuck in a rut - new inspiration can give their gaming new life.
But here is the thing. What can the book do that the other players cannot? Aside from costing money.
I have heard of but never seen the Hero Builder Guidebook, and what I heard of it was that it was a joke and not worth wasting $30 on. Use that money to watch LotR, Star Wars, etc and get some ideas, or if you have seen them already just use those sorts of things and spend the money on whatever suits your fancy.
As I said Mystara had an accessory that had things like that in it for players to help them build an outline and worth form, but it wasn't a big seller.
1st edition and all others referenced actual reading of real books and stories to pull inspiration from rather than giving lists of things.
Basically we are talking about a brown/blue/green splatbook from AD&D directed at the players. The blue books for the DM were to help keep the stories interesting rather than being just a dungeon crawl for those wanting more than a dungeon crawl.
HBG also wasnt that inspiring to many I know of. Yes my EXP is not the same as that of all, but that is all I can go on to form my opinion.
I think such things should be built into the game itself as older editions had but as newer editions came along was lost from the PHB. It was assumed that people had read it in past editions maybe, but left the absolute new play in the lurch. We still have Harry Potter, Eragon, Golden Compass, LotR, Hobbit, etc of fantasy setting movies a plenty right now that any of those could offer abou as good as inspiration than a book telling you what your fighter might want out of his life in the game world.
That is the biggest point I am trying to make. Back when there was little to relate to the game to give you fantasy stories everywhere that everyone had seen (I know there was as many then as there is now but now there are more people to talk about the movies with to hare ideas) the lack of inspiration is not likely to be gotten form a book wherein Clash of the Titans, TRON Legacy, etc can do just as good as well can the new D&D movie coming out and tons of other fantasy genre movies that have a group of people coming together to overcome some obstacle in their world. Even that crappy new Merlin series can offer inspiration if people are really looking for it and need it for the game.
