is it a dwarf? it should be a dwarf.
Why wouldn't you? Let the players do whatever they want, I say. If it works, fair play to them. If it doesn't, it's still funny.
A couple of players in the Shadowrun group I'm in made a fetish porn video with an NPC politician, then used it to blackmail him.
that's pretty much how I look at it. The problem is the DM of the other campaign is making us follow a storyline. That said she's surprisingly lenient, but things like prostitution are strictly forbidden. My campaign...I have 4 or 5 end goals in mind, which one they end at and how they get there is mostly up to them. I come up with missions for them, they complete them however the hell the want. Ironically, the DM of our other campaign is the one that's playing the 1/2 vamp swashbuckler/hooker.
Oh god...I can totally see my group doing that...except the Warblade would forget that they're supposed to be blackmailing the politician, and decapitate him. Probably while the 1/2 Vamp is 'sleeping' with said politician.
On another note entirely, today I learned there will be a Dr. Horrible Sing-Along-Blog Part 2!!!
