Well, I guess I need to buy the 3.5 rules. I took that Herald level test, and so many of them were trick questions for things that were true in 3.0, but not in 3.5.
I like the term 'partial action', thank you very much.
Anyway, I read the 3.0 PH cover to cover with great delight. Halfway through, I bought it. The signifigance of this was that I was a convert to GURPS that had given up D&D as being simply to unworkable for serious gaming. But, when the DMG came out I flipped through it and decided that I didn't need it. For one thing, it was vaccuous. For another, I found 'prestige classes' revolting. Lastly, the rules in 3rd edition are alot clearer, better thought out, and better organized than they were in 1st edition, but for the shear charm of the writing, 3.0 doesn't hold a candle to the 1st edition books.
The 1st edition DMG is filled with (looking back) startling bad advice delivered in such a colorful and eclectic manner that you don't notice. Reading it now I wonder how the game hung together for so long. But on the other hand I remember reading the 1st edition DMG for the first time and finding it to be a trove of mysterious secrets and power. Bad advice notwithstanding, the true measure of the value of the 1st edition DMG is that I feel perfectly free to forgo the 3rd edition one with its 'useless' lists of treasures (as if my own imagination could not more than suffice by this point) and such, but I would never give up my 1st edition one.
