This is a bad choice for Windows. This directory is not easily accessible to users using File Explorer, since only Desktop, Documents, Downloads are visible by default. Despite being located in C:/users/username, clicking on one of them like Downloads, gives you no way to navigate "up" (to C:/users/username), because Explorer treats them differently, and going up takes you to the root of the system. The user literally has find this by navigating from the root of the C drive, like some caveman

So what should the new path be? There's no clear answer, but the best place is in Documents.
About 80% of games I play, use Documents/Gamename (or Documents/companyname/gamename). So the path would be "%USERPROFILE%/Documents/TOME4".
Microsoft officially recommends using %USERPROFILE%\Saved Games. I'd say maybe 1% of games do this. I don't recommend it, because it's also inaccessible from Explorer, like TOME4's current path.
About 10% put them in AppData/Local. I don't recommend this, same reason as above.
And finally another 10% save to a folder in the game's installation directory. Usually indie games like TOME which have no installer, just extract and play.
