Okay, after the ending (which i found satisfactory yet predictable) I have thought hard and long about what it would take for Bioware to redeem themselves after "The Butchering" (heh) of Revan's story. A couple of possible endings would have to be placed in the next story arc for me to feel as though his story has sufficiently wrapped up. I think these ideas are relatively interesting, (from my point of view at least) but i'd like to hear input if you like the ideas. Keep in mind this is speaking from the speculation that Revan became Whole in the end and still seeks to help the player find some way to defeat the emperor as a spirit. Also take note that this post is focused on ideas for the Sith inquisitor and Revan's story as a whole, not any of the other classes. Forgive me if this sounds half assed or childish, it's 3 am and I'm half asleep
Number 1 (Dark Side). Being a Sith Inquisitor myself I would ask that we get the option to bind Revan's spirit and use his power to defeat the Emperor, or something of similar effect, maybe taking over the Empire with the new power or something if bioware intends it to be the absolute finale of the Swtor story.
Number 2 (Neutral). This one was tough, I had thought perhaps there would be some way the Inquisitor could find perfect balance as Revan did in his prime and finish the job that Revan started by following his path (or something of that effect, perhaps gaining a new understanding of his own power and connection to spirits, or learning some new ability or something).
Number 3 (Light Side). This, i think would be the most satisfying ending (especially for the die hard Kotor fans out there like myself who loved the Revan but wish he never had to die in the first place >.>) In this possible ending, Revan's spirit and Darth Imperius face the Emperor directly, Imperius makes some remark to the emperor about how he used the entire Empire (and galaxy) as a means to an end, then something about how "My chains are broken and the force shall free me" in the sith code is a reference to the Emperor using the Empire for his own goals. Imperius then argues that the Empire has the right idea but needs to divert away from the vicious part of it (Like in Azshara's conversations about reforming the Empire.) Revan would then say something about how the Emperor is super powerful and cant be beaten alone (Typical Hero banter). Then lends Imperius the remains of his energy fusing with Imperius. (i kind of imagine Revan and the inquisitors voice on top of one another or perhaps Revan momentarily taking control of the Inquisitors body to finish his work.) Fight ensues, yada yada, Imperius is now powerful from the super hero team-up ( xD ) and uses the power to defeat the emperor, Revan would then decide to stay with Imperius after his defeat, saying Imperius could put his power to better use than he ever could, and then Revan fades, and becomes one with the force entirely.
Satisfying ideas? Anything to add? Please tell me, i'd love to hear some input.
