I like games that are open ended and tend to prefer worlds with grey morality, but as-long as it's not a complete railroad and the stories good I should be fine.
It is somewhat important to me that games require a level of thought and planing, I don't particularly like games that amount to "go to X, kill Y, repeat" and generally prefer my PnP games to not mimic video game construction (which doesn't mean the can't be set in a video game's world).
I started playing D&D while I was at Case Western, but since leaving there I haven't been able to find a local group.
I've played several Games of D&D 3.5/PF and I've started a few games of GURPS, but those fell through (they were PbP games).
I tend to play Magical and/or Smart characters, though I can also play the gishier side of mêlée. When playing D&D I like to use homebrew when I can, otherwise I tend to pull stuff from mostly non-core books. My characters tend to come at things from odd angles or perspectives (and a relatively large number of them are moderately insane) which necessitate some level of depth and back-story.
