Yeah, I'm completely and totally done with D&D 3.x and D20 as it exists now. The 3.x ruleset is too deeply flawed for my group's playstyle to mess with, and ends up being less fun to play than other systems. And this is coming from a guy who has bought probably $7000 worth of 3.x/d20 stuff over the years. I haven't run 3.x/D20 in over 3 years now, and haven't played it in about 1.5 years- the thought of running another 3.x game gives about as much joy to consider as undergoing another right side thoracotomy. The D&D 3.x and D20 books had some good ideas, but horrible implementation IMO, but they are still useful to mine for ideas.
I'm cautiously optomistic about 4E- I love the flavor changes, and the mechanics seem tighter, more streamlined and much easier to prep. In the meantime though, we'll stick with the four games that we've heaped our love on- Savage Worlds, nWOD, WHFRP2, and WH40k: Dark Heresy.
