Not if you're the parent buying the books for a kid. Parent walks into a store, asks what they have to spend to get a kid without a group yet into D&D, the store owner will point to the PHB, MM and DMG. That's $90. That's a lot to drop on a "We don't know if he'll like/do it".
And if you're a kid, $90 is a large drop in the bucket.
Hell, I want to give the new books to a kid and I feel $90 is a lot.
Well, yes and no.
I wouldn't spend that kind of money on my son's friend at a birthday party.
But if my son wanted to learn to play the guitar or trumpet, I'd go for it at that price. (or even up to $200 if he was serious).
If he wanted a season of sports lessons at that price, fine.
If he wanted to engage in my very favorite hobby with me at that price...hells yeah!
$90 is both a prohibitive and trivial amount of money...and that distinction is made by the priority of the object the money is spent upon.
My son (age 6) already has inherited one of my 2e monstrous manuals, my 3.0 monster manual, and the WotC book of dragons and book of monsters (can't remember full titles and I'm not waking him up to find out).
That's approximately $30, $30, $20, and $20, if I'm estimating correctly ($100 for NOT EVEN PLAYING THE GAME). I'm not rich. I'm sharing my own hobby and it's history with my son (he also has my old MASK and Transformers toys...none of which are in Ebay condition).
He knows the types, breath weapons, and ecologies of the dragons (chromatic, metallic, and gem). He has favorite dragons (mercury and crystal). He has favorite other monsters (medusa, hydra, catoblepas-lol-, thokka/thoqqua--for some reason, and more).
I dunno...I guess I'm rebutting that gamer dads are unwilling to drop $90 on a game to share with their sons (where sports dads might drop $500 on lessons, practices, equipment, et. al. for their own sons).
