I assume we're talking about The Old Republic here?
Naturally, both. I want all the stories for all the character classes. However, initially I'll go Jedi. What I'm curious about, however, is the extent to which Light/Dark Side points influence the game. If I go all out Light Side on my Sith Inquisitor, will I eventually defect and switch over to the Republic? Likewise, would my Dark Side Trooper eventually join the Sith Empire?
If we're NOT talking about TOR, then I'd go Neutral as well. I'd probably hit up the Jedi temple for some free training first, and some basic gear (Lightsaber, Cool Robes, Unwaveringly Loyal Astromech Droid) before telling them all to go fuck themselves (except Yoda and Mace Windu, those guys are alright) and heading out on my own.
