Ok that is good to know there is that you'll have a choice between the two. Thanks.It´s new game plus. If your character is below level 30, he´ll be raised to level 30. So I guess you´ll have the option to start a new game - you start with level 1. If you start a new game plus, you´ll start at level 30, or the level you had when completing the game. Whichever is higher.
@Marcin Momot any chance of them fixing the level Discrepancy from When you first obtain a ship to go to Skillege Isles as it's way to high. You see when you get there the Main quest with Yennifer after the funeral starts @ 16 and it's grey and you only get 5xp for that one and many others.
