The Pros and Cons of 3E (IMO)
Well since I have been pretty vocal about my gripes concerning 3.x D&D over the past few weeks (probably because I am in the final months of DM'ing the current phase of my 3E campaign, and am starting to find statting up NPCs and monsters about as much fun as prying off my toe nails with a hot butter knife), I may as well chime in here.
Like you Belenumeria, I am amazed at the gap between "theory" and "practice" in d20. When I first read through the 3E books 4 years ago, I thought the "unified mechanic" solved so many problems. Two campaigns (as DM) later, it has proven to be the slowest FRPG I have ever played -- and has certainly involved more rules consultation than any other. (That problem, of course, gradually diminished over time, although it has always been a bit of a race between greater familiarity with the rules, and greater options available to PCs and NPCs at higher levels).
There are a lot of things that I
do like about 3E, and I will be happy to play in another DM's campaign in the future. But I just don't have the time or inclination to DM 3E D&D ever again. Other systems are a lot more fun for me.
3E D&D accomplished two things.
It gave the game: (1.) a more consistent rules system (the 'unified mechanic' of d20, etc.).
But, in order to play the game, it required: (2.) much more game data (just compare an average statblock for 3E with a statblock for any other edition of the game).
I applaud 3E for accomplishing (1.).
I loathe it for accomplishing (2.).
(1.) Encourages creativity and DM innovation.
(2.) Discourages creativity and DM innovation (as any change affects many other aspects of the game, and has all kinds of "unintended consequences"). And dealing with (2.) is a complete time suck. Maybe if I were still in high-school, or an undergraduate, (2.) would not be a problem. But it is for me now, in my 30s.
Given my limited time and natural inclinations, (2.) has proven to be a major pain. Others with far more free time than myself, and/or a more "gearheady mindset", obviously disagree.
But after I finish DM'ing the current story-arc of my 3E campaign, I have had it. I will never DM 3.x D&D again.
I still love D&D!

Just I just need a more 'rules lite' version. (This is why I'm giving C&C a shot next time.)
