Let's start it out with a biggie: D&D is not my favorite RPG.

3) I hate bookkeeping. Unless there are good reasons for it (like playing an adventure where survival is an issue), I don't want to worry about tracking rations or ammunition or the like.
Took the words right off my keyboard.
I never, ever use random tables. I will intentionally design an encounter to serve as a "random encounter", but not just roll for it. Tables are sources for ideas. To go with the idea of the above, I don't do "randomness". To me, the dice are there merely to answer the question "Does it happen?"
Rarely do I ever deal with absolute alignments and, or even very hard "This guy is evil" things.
Human-centric games (and human-and-elves-dwarves centric games) bore me to tears. I love the crazy, the weird, and monstrous, and think a game lacking the core races would make me happy.
I consider an RPG a tool. If you want to play a game that focuses on X and Y, it's better to use a system that X and Y were designed to emulate, then try to make system Z do it.
Traditional Tolkien-esque Medieval Fantasy grates on me a bit.
Fighting rats, wolves and skeletons at 1st level is offensive, and fighting kobolds and goblins has been done to death.
I hate resurrections.
I'm ok with railroading sometimes.
The Planes hold little interest to me (outside of say, the Feywild).
Never liked minis (in the "buy or paint little plastic characters" sense).
