Depends on your goals for the game.
Most of my games are original. My games are 'packed in'... so I only need to expose 1-2 decent sides off of any given row of games
Though, most of the art on my games is actually pretty decent with a few exceptions.
control panel overlays are where a game's condition is most visible, so if that bugs you, I would consider changing that if someone has a repro for it.
The rest of it (based on the pics) looks pretty decent, and I'd just clean/touch it up and enjoy it.
Some collectors like their games to look as close to as they did when they rolled off the factory assembly line (if not better).
I can't help but think though about collector cars.... the old path was restore restore restore..... but collectors have come to realize they are only original once. So now many times a nice survivor car can outvalue a beautifully restored one. Who knows if games will ever go that way, and that isn't why I don't try to restore mine to mint.... but it is an interesting point to reflect on....
