Installing Linux doesn’t magically transfer over all your files. My comment did not reference the time taken to install Linux. Additionally, for a first time Linux user, it may not be immediately clear where certain things, like mods or save files for games need to go.
EDIT: you’d also have to install and set up all your software (independent of which OS you install). None of this is particularly difficult, but it takes time and you need to think about it in advance to avoid missing a bunch of files or programs
