When I saw the anticheat variables in the game thread I was tempted to bin the game, despite it being really one of my favorites.
Single player Mods and Cheats are a service to game developers becausethey expand the player base, and that is especially true for in-developement games.
I can imagine to replay different routes for a complete game I like a lot: I let the game rest some time, start it again and play differently.
But keeping 3 or 5 saves with different personalities open for a year or so totally destroys immersion: i can't remember who I am, what I did and what I want to do.
That's why I like this mods that help play the most of the game in a single manipulatable save, or later just to take some deviaton from the path without major consequences to cut out your route.
To remain to this developer, I did replay Acting lessons once it was complete.
Another good example is melody: 1st time play I messed up with everybody, then replayed it with an intended route in mind.
