yes bliznez, you chose your ending but only endings SPOiLER
like i said only endings, you dont get many choices of dark side or like side during the game its not like kotor, its only at the end that you have the final choice, and each choice gives you a very nice costume.
SPOILER END
Well frost saber system is different than jka and so is the game, its a different game so its sure there are different saber system, but at least you have the chance of slowly the moves down by pressing slower to make different attacks, and they also said that they worked hard on making the system because he is weilding a backhand and they wanted it to be very realistc spins and move so they needed to think alot on his moves.
