In most MMO's I've been a part of, the more mature player base is the perceived 'evil' side. So I'll probably go Sith. There are a number of Dragonwolves that want to go Sith, but also a number that want to go Jedi. Some of the back-and-forth postings are hillarious to read.
Sentrosi: And, for those wondering, I will probably be fighting on the side of the Sith.
Daleon: Sith is likely going to be choice also.
Warwolf: I find myself liking the lightside more personally.
Asp: Excellllent... Smithers, release the Banthas!
Sentrosi: Daleon, it is useless to use your voice to convince those who follow the light. Let your saber be your tongue, and your slashes be your voice.
Manitou: It only takes one small flickering candle to dispel the deepest darkness.
Asp: "Your feeble [candle analogies] are no match for the power of the Dark Side. You will pay the price for your lack of vision. "
Warwolf: You can have sight and still not see all around you
Asp: Confucious say: A dead cat with no wings cannot fly..
See this is why that jedi got smoked at the end of that trailer.. He spent too much time in philosophical poetry class instead of lightsaber training..
