In case you didn't know, 3e brought back a lot of gamers who ditched D&D a long time ago. There are a lot of people who quit AD&D when 2nd ed. came out that came back because of 3e, and a lot of 2nd ed AD&D gamers who quit that were brought back with 3e. Personally, I only played 2nd ed. because it was the only game and town, and I was desprately trying to find gaming groups that didn't play AD&D. Before 3e came out I was almost there, taking part in a Champions game and a GURPS Fantasy game, but stuck around for the AD&D game because the DM and players were good. But I did not respect the system.
I rolled a "1" on my save for 3e. 2nd ed. needed killin', yer honah.
I don't understand why people believe they "have" to buy anything other than the Player's Handbook to play D&D, or the core three books if you DM D&D? You don't "have" to buy anything else to play D&D. Heck, you don't have to buy anything if you just want to run a roleplaying game. You can download free rulessets off of the web and not spend anything at all. There are options for the gamer on a serious budget. They just aren't going to come from WotC. When I was playing 2nd ed, my DM only used the core three books and the Psionic handbook. That's it. And that was right before 3e came out, with a ton of 2nd ed. product on the market.
WotC is not a charity, and it's not a government agency. They exist, like all other companies, to generate profit. And the way they do that is by producing product that others will value enough to exchange their work ($$$) for WotC work. Not everyone will value their product this much, and that is to be expected. And it doesn't mean that they have to lower their prices.
So, please explain why you "have" to buy a whole lot of books to play D&D? You know, you can still play AD&D with your 2nd ed. books. Heck, there are 1st ed. AD&D groups still playing even now.
