I spent 125 hours in this game, loved it since its release, loved the story, my eyes were filled with tears at the end. I had bought Phatom Liberty on GOG as soon as I could pre-order it. When the latter released, I downloaded 2.0, and started the story from scratch to experience the whole game without interruption. When I realized there was level scaling and no more grading of the dangerosity of the missions based on you current level, I did ALT-F4 the game in distgust, and refunded Phantom Liberty. I won't touch it again, unless appears a way to go back to the non scaling version without at the same time loosing all the improvements of the 2.0, and being able to play Phantom Liberty that way as well.
