...over time... ...long term gamers...
We are in complete agreement.
But one of the goals of D&D 4E was expansion. "Experienced" gamers were no longer the target(s) (IMHO, etc, etc; we were certainly invited along for the ride, but we weren't the targets).
And, if the options are, sell to "Experienced gamers"
or sell to "new players", it's possible WOTC deliberately chose to leave the experienced gamers cold, to increase the game's attraction to new players.
There's an argument that an internet forum about gaming is self-selecting towards experienced gamers. We don't know - we can't know - how D&D 4E does with inexperienced gamers. Maybe they adore 4E adventures, and would flounder helplessly in Paizo's Adventure Paths.
I know when I was less experienced "adventure" meant "dungeon", and adding a wider scale to the game took time. In my teen years, I'm not sure that D&D 4E, and the modules produced for it, wouldn't have been exactly what I was looking for.
And if there are more teens buying D&D "stuff" than experienced gamers, that might explain the situation.
In fact, I think I've just found my new Pet Theory.
Edited to add - I actually game (Pathfinder) regularly with two under-20-year-olds who told me they were "into gaming" with their friends and "play online" (text games) "all the time". In Pathfinder, one of them eagerly role-plays and explores complex character scenarios, while having no idea how to read the character sheet; the other repeatedly says she loves game and loves coming, but seems very intimidated by both the rules-set and the actual "improv" nature of roleplaying.
I'm seriously wondering how they'd do with 4th Edition.
