My first character, ever, was a OD&D thief ('92ish?). I think it forever marked me. I tend to gravitate more towards theme and abilities than specific class.

My two favorite archetypes are the sneaky, stealthy spellcaster (such as illusionists or my own shadowmage) and shapechangers (whether they're druids, transmuters, or egoists). I like playing character classes with presence and an ace or two (or ten) up their sleeve.

I occasionaly play a wanna-be paladin, just for a change of pace, but I avoid the actual paladin class in lieu of a gish of some sort.
