They need to be played because KOTOR 1 was one of the best games ever made. That's reason enough.
I FULLY agree.... and I also think Disney should look at that game as the basis for a new Trilogy.... Reven would make a GREAT main charachter... I can care less about that happens after EP. 6 and a old Luke and Leia and Han Solo ready to croke and poop his diaper.
