Test I took last year said INTJ.
Before that it was INFP.
Thinking about it I'm definitely an introvert. I feel more relaxed doing solo things, but I'm not shy. And questions like "Do you feel comfortable in a large crowd?" are a little pointless to me. I DO feel fine in a crowd. It's not a big deal really. However I don't feel extra energized by it and mostly I like to "swim" in the crowd and plot out my travel plans. It's easier to keep to yourself in a large crowd than a smaller one also [everyone's too busy talking to someone else to notice you]. And there's the random pretending to be a secret agent thing that makes like more fun during a crowd.
Anyway, definitely an introvert.
Sensing and iNtuition, well I'm more of an idea head in the clouds kinda person. However Questions like "Do you seek out a new idea of use the tried and true method." are also misleading. If I'm playing Soul Calibur with others I have "practice mode" and "WINNING". During the former I try new things and evaluate what's going to work and what isn't. The latter I just do what works.
Thinking and Feeling. I tend to follow logic a lot despite being a very emotionally driven person. I'd guess I'm closer to feeling than thinking since most logic steps to come from me seeing it work while growing up and thinking "Yeah... gotta think things out so shit don't get out of hand."
P and J. I have the most horribly messy room at the moment. But all my dvd's are organized. When I play any game or do anything I have a plan. One with contingencies too. However you can never plan something out perfectly, you have to be able to adapt and improvise. Improvising also won't work by itself. Here I'm more J than P.
So, INfj would be pretty accurate. An INfj that's not afraid of socializing, just doesn't really care.
