I have to disagree.
As I said, all that was needed was, at most, 3 books.
Of course yes, they still followed up with publications, but all of them were either modules, or 'supplements'.
That's not how I ready what you wrote. It seemed you had two concepts: 1) you only needed 3 books, and 2) the business plan was to dupe you into buying more books every few months. The sentence I quoted didn't include anything about core books only.
Second, all you need to play 4e is a DDI subscription, or just the PHB and MM (you don't really even need the DMG). You don't NEED PHB2 or MM2, any more than you NEED MM2 in 1e.
1e required at least three books, and most DMs bought at least the Fiend Folio, MM2, and Deities and Demigods, along with a setting and often a bunch of modules. Players often bought one of the expansion books as well. It was essentially the same model, just a bit more chaotic, less routine in scheduling, and more module focused.
It was meant to have the negative connotation.
If people like to look at WOTC as a resource for content, that's fine.
But the original spirit of the game was that content was up to the gamers. Perhaps contemporary gamers are just lazier..... ?
I disagree. The original "spirit" of the game was also to feed additional content to gamers from TSR. Heck, 4e still is far behind 1e as far as published products go so far.
1e was well known for tons of modules that gamers ate up, in addition to other books. That is content handed to people. It seems like most 4e games, so far, are made up by the DM. That is gamer-created content as well.
And then there were the supplements in 1e of Unearthed Arcana, Oriental Adventures, Dungeoneer's Survival Guide, Wilderness Survival Guide, Manual of the Planes, and lets not even get into the settings and modules and gamer aids and such.
So I am not sure where this idea that 1e was not content driven by TSR as opposed to from gamers. It COULD be gamer-driven content, but no more or less than 4e COULD be. But both models try to sell you more stuff, and both models do not require that you buy more stuff to play the game.
And, as for your implication that those who like 4e are both lazy and being duped, well, how about we let that one go, OK?
