I've been cataloging user files for the past few days and only now have looked through this thread. The wiki could do with better documentation of the nuances because I don't really care to read multiple forum pages of back-and-forth to find answers.
The "Name" field in the Game Version should be "File name". When cataloging I've been doing the bare minimum necessary to add the system (copying the game name and leaving the region as U, unless I know it was only released in a certain region).
For sorting, I'm more used to ignoring "The". The site could support this by having a separate sort name. For a Wikipedia example,
The Simpsons: Bart vs. the World has a default sort key option like
{{DEFAULTSORT:Simpsons: Bart vs. the World}}
which will sort it that way in all the categories it's in. There's also an additional
[[Category:Video games based on The Simpsons|Bart vs. The World]]
so that specific category will sort it in that way (having every Simpsons game sorted by Simpsons would be unhelpful).
Whichever way, the inconsistencies with "The Game" and "Game, The" should be removed. I don't know of a good way to search for existing examples of the latter.
