I wouldnt want the Exile and Revan to be apart of the next kotor. They are just to vague characters on the count of every player having created them in theyre own image. Would rather see what happens after they both are gone. See a fledgling new jedi counsil and maybe some sith left behind after the lords fell.
I would also want to see Kreia stay in the series if only as an idea. Maybe theres a new dark Thraya in the galaxy. Maybe kreia walks in the minds of another student like she walked in sion. As she said: there must always be a Darth thraya. Kreia was the best character of in kotor history and maybe game history.
Would also like to see more cutscenes with action. There was alot of cutscenes but mostly they just stood there talking so a bit of witfull banter exchanged with some ligthsabers flaring would be nice.
Dont subscribe to the idea that the character should go off to the "sith empire" and figth them. Maybe just one true sith would come to the outer rim. And gather the remaining siths, Maybe hes searching for someone, maybe Revan had a child. that could be the new character. Maybe the child was hidden away while revan brougth havoc to the sith. hmm might be babbling a bit here
But i would like the focus to stay on persons and not machines. To be about feelings and not weapons. Dont like that siths relies on death stars and star forges want it to be about philosophy and faith.
