Lessee...
I like the variety of options on classes, races, and everything else that we've been provided, and hope it only expands.
I like elves, gnomes, and oddball races.
I tinker with and sometimes entirely rewrite everything, and have a couple hardcovers' worth of such material, most of which I'm using in the game I GM.
I detest WBL and the "resource-management game", and provide opportunities for characters to get much more or less money than expected.
Except by seizing such opportunities, an adventurer in one of my games will never match the wealth of a successful merchant, let alone a noble.
I like high-magic settings and mixed technology levels, and enjoy plotting out the origins and social consequences of them.
I prefer sentient, civilized adversaries, and like running a crowded world that isn't just the PCs' playground.
I dislike mechanical optimization that doesn't fit character concept or a reasonable character's decision who doesn't know the mechanics behind the scenes. A good deal of my tinkering actually punishes hyperspecialisation.
