Does race matter?
Solution 1:
Bioware have confirmed that there will be "active social" differences between the races, but there isn't anything that will affect the gameplay, just cosmetic differences.
Here's a list of the social abilities as we know of them at the moment:
Human - Rally: Rallies nearby allies.
Miraluka - Sense Force Alignment: Senses the target's alignment with the Force.
Twi'lek - Parlor dance: Perform an unique cultural dance.
Zabrak - Inspire loyalty: Inspires loyalty from nearby allies.
Mirialan - Focusing Ritual: Undergo a focusing ritual to rest and recuperate spirit.
Cyborg - Scan target: Scans target with a critical cybernetic eye.
Sith - Punish: Punish your companion for his or continued failures.
Rattataki - Shadowbox: Perform a series of mock blows, blocks and counters, warming up for the fight to come.
Chiss - Salute: Prompts nearby allies to stand at attention.
