Yes, I would buy the Directors Cut version.
I actually would pay the full price of $49.99 provided that everything was complete.
By complete I mean that there are no bugs or glitches. There are no doors that go nowhere. There are no missing quests. It is LIVE enabled so that the developers can (and will) create new planets and quests.
We all know that this will never happen though.
I wish I had seen in K2 that the colors did something. Let me explain.
We all know the basic color scheme.
Red - Sith basic color
Green - Jedi Consular
Blue - Jedi Guardian
Yellow - Jedi Sentinal
Have the colors mean something. If a Jedi tried to use a Red crystal there was a dark disadvantage. If a Consular tried to use a Blue crystal it would be slightly unweildly due to it's intention to be used by a Guardian. If a Sentinal used a Yellow crystal there would be an advantage that would benefit just Sentinals.
Violet is kind of a mix of Red and Blue thus has Sith Guardian benefits.
Orange is kind of a mix of Red and Yellow thus is a Sith Marauder.
Viridian is to a minute degree a mix of Green and Red so it is used by Sith Asassins. Or make up a better combination of Red and Green which normally create Yellow.
The metals have a benefit that is not Class or Dark/Light side dependant. Silver has one, Gold has another, Bronze has yet a different, etc.
