Super interested, have sheets ready to go, but as above I'm a little concerned with the ruling on villains as playable characters. For instance, Green Lantern blocks out Sinestro, who's a perfectly good character - he even starts a hero and his fall is a great arc to play out. And if BlackSam got Batman, he's suddenly controlling a good 10+ characters all with their own well-written personalities, backstories and plotlines to play - for instance, Harvey Dent, another hero who falls and arguably (or at least [i]I'm[/i] arguing) a more interesting characer than the Knight himself (and also one I'd like to play as a secondary but that's neither here nor there).

Plus, the Hero/Villain dichotomy is super fun to play against each other, and with a little in-house cooperation it's always exciting. 

In any case, I'm interested and I'll have a Constantine sheet up and ready to be approved as soon as I've snipped it enough.

P.S. Is it a flat requirement to fill out the arc pitch section of the CS? I have many arcs to play with John but giving a good three of four of them away seems to spoil the fun somewhat.
