no crunch, thanks
I voted for no crunch because that's what I mainly look for. I really don't need a bunch of new rules to run my D&D sword & sorcery fantasy game.
For example, I don't like the Conan OGL main book. As far as I am concerned, that game is unplayable due to new crunch; and every member of my gaming group agrees. I find The Road of Kings quite good, however. It presents very little new crunch. The book is essentially a gazetteer. If I ever get around to d20 converting and running an old module for the 1985 Conan RPG, I'll make use of TRoK; but it will be Conan D&D.
Similarly, I don't plan to use any of the crunch from Mesopotamia besides the alternate human races and the domains for the new deities. New classes (even just prestige classes), feats, magic rules, spells, etc. are generally unappealing to me. Fortunately, the adventure parts are not dependent on using that alternate material which I find to be one of the greatest strengths of that product.
A d20 (D&D) game set in a different, non-fantasy genre is another matter altogether. I love Judge Dredd and Omega World because they change D&D just enough to make sense for those genres. The crunch in those settings makes sense. It's not just rules bloat.
