That's the big fun of being on a Roleplay Server, really. So yes, I *do* Roleplay my characters as their own individuals.
On one side I have a brash girl, that loves to have barfights and pissing on everyone's knee who's not respecting her to an appropriate degree.
And on the other hand I have a shy, clumsy and introverted Trader, trying to keep away from the fray, rather paying himself out of extortionate prices, than risking to be blown up into space.
And on the other other hand I have the calm and collective, yet determined and loving scientist girl, caring for her friends and family, as well as her sadistic and cynical father with a permanent dark mood - who I also RP myself.
None of these guys are ooRPly influenced in any way, other than occasional slips, where I accidentally metagame minor details, because I forget that exactly that character doesnt know something that others and I do.
