Speaking with PC Gamer, Game Director James Ohlen spilled a few more details about what he calls the "Gray Jedi" playstyle, which will be supported in an unspecified upcoming patch. Gray Jedis (or Gray Smugglers, Gray Inquisitors, etc.) happen when a player creates a balanced mix of light and dark side choices over his or her career and ends up staying in the "neutral" zone on the alignment meter. Because the game currently incentivizes strong light or dark side playstyles with specific rewards, neutral players are left out in the cold.
Fortunately, the system that's coming will cater to these dirty, filthy neutrals. "We don't want to force people," Ohlen said. "Once we get to the next stage of our light side/dark side system, you'll see the rewards. Light side, dark side and the gray items will all get more powerful."
