Well, basically, I sense when someone wants to roleplay.
It goes from
"oh not again!"
to
"oh corsairs, hail! I was just bringing food to crete.."
But then again there's those that stay silent or that talk nonsense. But I even prefer those that talk nonsense to those that just keep quiet like entire ship is actually DEAD.
I find i t that with people that love to rp, I don't even have to use a CD when they know they're caught. They just shut off the power and prepare their wallet/cargo and skilled fingers to type down few moments of much appriciated roleplay.
