rogue. and wasnt that sort of what the exile was anyways? atleast in terms of choices and which path you could follow throughout the game.
as many people have said, this is a star wars game. good and evil epitomizes what the whole ideal behind star wars is about. would being able to play as a 'grey' character be interesting? you bet. but it just doesnt fit the star wars mold and id rather it be kept that way.
not sure about this part. i dont think the number of lines of dialogue determine quality of the game or story. its all about how well written and presented it is. as for the development cycle i dont think there should be a specific time frame. i think the time frame should reflect what needs to be done and how long that will take. saying that it should be 2-3 years doesnt necessarily fix anything. if a project only takes a year to make, then whats the point in having it lingering around unreleased for another year? at most, a couple of extra months of bug fixing and QA sessions, but thats about it. so therefore, it should take as long and as little to develop as the game requires.
i have no clue what you even mean here since you didnt bother to actually give an explanation of what you view as 'different and unique'. many would argue it already is unique.
again, this is rather subjective. the kotor series, for all intents and purposes, has been a 'defining game', atleast in terms of star wars games released.
