Would it work if i transferred my old saves into the new version?
It should work if the save is from recent version (2,3 demos before the current one). I don't reccomend doing it, but if you do, please let me know how it went :-)
The option I do reccomend, however, is starting the game via "New Game" and then selecting "Continue from a specific point in the story" and then skipping from there to where you were the last time.
