There would be almost no point to that.
This game is about the journey, the discovery, and the choices made (and entities banged) along the way.
A complete/mostly complete save would lock you out of seeing
so many one-time events and quests (and even though there
are a lot of NPCs with repeatable scenes as well, you would have missed their introductory scenes/quests and have little to no context about them).
Note that there is no "gallery" feature to go back and see whatever you missed. If you wanted to retain easy access to a specific one-time scene, you would generally make a manual save right before said scene and archive it carefully.
If you do not want to put effort into the combat/leveling/gearing up portion of the game, then after starting a new game,
You must be registered to see the links
until the game is as easy as you want it to be.
