We have this issue with the Nintendo games that will put the Nintendo Country Code in the title, but these are entries made unknowingly or before we put up this thread with the list. Ideally, we would not have the country in the title at all, and have some other way to display this information.
So no, for now it should be [FR][NL]... The only case where that item number would be used is if there was 2 releases to avoid a name collision. For example this happens with Nintendo games in Germany, where you end up with two entries like so:
Game Name (NOE) [DE]
Game Name (NOE-1) [DE]
So no, stick with using TLD on the title for everything... as I have typed in other posts, let's try to keep it simple with some of these things, so we don't need to keep a complicated list of do's and don'ts for certain things.
