I liked K1 story much more....before K2 came out I remember reading about it and one of the devs were talking about how they didn't want to try and deliver a more powerful story then K1, but focased more on combate and gameplay.
You gotta love Kreia at the end though, when your talking!!
"Did you think I would tell you some secret that would shatter you to your core? There is no secret. There is only you."
It was like in direct defiance of K1's story hahaha
