So, based on the answers, I'm assuming that the 3rd person sight applies to actually controlling your actions. In which case, I too would want the switch-between-1st-and-3rd-person-view deal, and would probably use it to check out girls without them knowing, just like everyone else has said. I would like to observe myself from a different perspective, though. See how I really look to the world. Maybe find out what I can do better, all that jazz. As long as we're on the topic of new perspectives, I'd also like to see things from other people's point of view, complete with a knowledge of what they think.
