I haven't decided on my character for my first playthrough yet, though. I want to pick one who I think would naturally talk to everyone and explore everywhere, so I can see as much of the game as possible without sacrificing roleplay, but beyond that I'm still dithering!
Yes, a difficult choice. And I can see the appeal of having a very explorative first playthrough. But wouldn't that leave less to be experienced in subsequent playthroughs? Perhaps it is possible to have several truly unique playthroughs, if one walks a narrow path (and abstains from spending time on forums).
