Once upon a time, I sat down at an introductory game of 2nd edition Dungeons & Dragons - and my life was changed.
I don't mean to sound like I'm obsessive, or like I'm one of the stereotypes that people worry about after that awful Mazes & Monsters movie or the case of Dallas Egbert (which, by the way, I got to research for an academic paper), but D&D did have a lot to offer me, especially as shy and socially awkward as I was when I began to play. My D&D group became a safe place where I could be part of something, part of a group, with people who wouldn't sneer at me because I spent most of my time with my nose in a fantasy novel and my mind in a world of dreams. By the time I went to college, I was hooked enough that the desire to find a group with which to play pushed me to make contact with other people, something that was generally outside my comfort zone but which resulted in me developing a group of close friends.
I will take on the challenge of almost any character. Mostly I tend to stick with good- or neutral-aligned characters, especially scholarly bards. Despite my bardic affinity, I think my favorite character is actually a paladin, though she didn't become my favorite until she lost her paladinhood (go figure). I love the opportunity to do in-depth roleplaying that uncovers new facets of my characters, and I'm perfectly all right with my characters going through horrific things as long as I'm with the right group of people and no one is taking such things too personally or getting too upset by game happenings.
Anyway, I believe that's enough babbling about table-top games for the moment.
