Really? Wow.
I never got how dice pools are more crunchy? Especially in WoD. Take as many dice as your dots or ability number (in, for example, SR), roll, count the successes, done. I always considered it more easy-to-grasp and intuitive than any version of keeping in mind D&D's myriad modifiers from turn-to-turn.
It was an era of overly complex rules systems of one stripe or another. My first RPG was a MERP set my mother bought me when I was 10 or so (Middle Earth RolePlaying, which used the Rolemaster system), and it was just charts charts charts. the next was Earthdawn which my friend bought; I was maybe 13 or 14. That one made enough sense to play, and we did, and it was great.
But then I found 2e D&D, and it was so elegant and simple compared to the others it blew our minds. The Earthdawn setting was great, but the mechanics were wonky and the dice pools and steps were just clunky. D&D, with its simple "roll a d20 and add modifiers" mechanic, was astounding.
We never managed to get a sustained WoD campaign going, largely because, again, the mechanics seemed so finicky compared to the elegance of D&D. We have Castle Falkenstein a shot (based on the positive reviews it got in
Dragon Magazine), we played a game called Og for a while, some of us ran Marvel Superheroes and Star Trek and even Toon, but we all came back to D&D. It was just an easier and more flexible system. Almost everybody knew how to play it, and it was simple to introduce new players who didn't.
Again, this was at a nerd farm of a high school, and we lived on campus so we saw each other all the time. But even after graduation, whose of us who went to (and ultimately dropped out of, but that's a different story) the same college kept going with it.
THAC0 was easy. The core D20 system that replaced it may have been
easier, but it wasn't by too great a margin.
