Connectivity precludes a full post today, so I'm going to ask a question. I asked the same question on Twitter, and I intend to write about the answers I got, but I figured I'd ask here, both for those who don't use twitter and for those who do but want more than 140 chars to explain their position. So here's the question:
If you were to play a game set in the DC comics universe, how quickly would you figure out that Clark Kent is Superman? Presume that you are in a position to interact with both - You're Metropolis PD, Daily Planet Staff or one of the other interesting citizens of Metropolis.
If the answer changes based on situation (such as depending on the character you're playing) then feel free to say as much. Similarly, if there's a reasonably simple "it depends" go ahead and let me know. That said, don't worry about obvious exceptions like him directly revealing it to you.
The answers I've gotten so far have been incredibly informative to me, and I can only imagine that a little more room to speak will make them moreso.
PS - And because, as noted on twitter, I'm not looking to trick anybody, I'll reveal my answer up front: Never.
