Hasn't anyone noticed that the Kreia storyline and the Revan storyline are unrelated, or related only in the sense that they are strung together with saliva and sheer will?
Okay, so T3-M4 is sent back, by Bastila, on the Ebon Hawk to retrieve the Exile to help Revan fight the mysterious gathering evil on the Outer Rim...
So they plunk Kreia on the Ebon Hawk and the entire story is about her madcap plan to destroy the force through you. The Revan material actually has no place in it, and vice-versa. The only links, which I'm sure the apologists will dig up, are there by pure fiat.
It's not about dangling plots, or mysteries or ambiguities. It's about two wholly unrelated parallel plots.
The whole real main plot also seems to be entirely about Kreia. Lame. The story is NOT supposed to be about some NPC. It's supposed to be about the protagonist. Like BG, BG2, and Plancescape: Torment, and even KOTOR 1.
