Well, I completely misunderstood this thread. By the title, I was under the assumption that the subject of the thread was more along the lines of picking a character class that closest resembles you in real life. As such, I voted for Other (Bard). With my winning personality and musical talent, there's really no other choice. Although I do like studying kung fu...
Regardless, as to the actual question, I don't stick to one type of character archetype when I'm gaming. Sometimes I feel like being a sneaky cutthroat who actively steals from the party. Sometimes I feel like being a giant of a paladin who pledges to defend innocent NPCs everywhere.
It really depends on what speaks to me for the given game and/or world setting. I usually start with a core story or gameplay mechanic that I want to use and expand from there. When doing table-top games, my choices can also depend on my fellow players. I like making characters that fit the group dynamic. In my core gaming group, we usually engineer characters as a group and have to come up with a tie to at least 1 other player in the campaign prior to the adventure hook (which eliminates the "random adventurers who just happen to meet and embark on a quest to slay an ancient evil" trope).
