With regards to RP and "IC" stuff, Bioware are going to have some specific RP servers,
although RP behaviour will not be enforced.
From a personal stand point my idea of creating a outline Backstory was to give me some motivation indicators
for each of my toons/ alts so I didn't play the story game the same each time.
I wanted to see if by using these motivations I could avoid the situation where you only picked answers/ responses
that resulted in Uber loot (story/ quest chains). This wouldn't apply to PvP situations (realistically) but I was interested
in seeing how far I could go with the PvE content without just falling back into my own personal morals.
For the Jedi Knight on Tython, one of the decision quests is where you have to stop/ help a pair of Padawans in Love.
If you don't stop them (dark side option) you are rewarded with a Lightsaber crystal, if you do stop (Light Side)
then, I believe, you get nothing but XP.
So which way would you go if playing a goody two shoes Jedi?
Tempted by the loot or stick to your characters motivation?
I know in previous MMOs you sometimes have no RP at all, I think that the RP servers may actually do well for TOR,
due to the fanatical fan base and story orientation.
