C:\Users\Username\Saved Games is a thing. Not a lot of games use it though.

There's also C:\Users\Username\Documents\My Games which seems more popular with some devs. Though some devs inexplicably use the base Documents folder, which is just obnoxious.

But yeah, a lot of devs still use AppData. I read a post from a dev once that explained the advantages and disadvantages to each Directory, though I can't remember the specifics, there is at least logic to why saves get stored in so many odd locations.
