The Realms of Arkania series had a system in which you either imported your characters along with their levels and stats or you created new characters with stats deemed appropriate for the new game in the series (I remember it was level 6 in the third game). If your imported characters had a lower level, you could choose to either import them as they were or let them level up to level 6 automatically first. It would be the equivalent of starting KCD2 at level 20 and expanding the levels.
I would quite like to see an end to the teleporting chest. It makes it too easy. How about Henry has a different chest in every location but remembers how many items are where (and perhaps what type - this could have a tab in the inventory). Just some ideas to make the game a little more challenging.
