I can already tell this is almost certainly a very stupid question, but I noticed the THE here and at the end of my other witcher games and I thought I may as well finally make use of the GOG discussions for once.

Edit: Im too newbie to know how to change this to a question, truly I am a novice

This comes down to the English language. The most common word in the English language is 'the'. Now think of all of the games, films, books etc. that begin with the word 'the'. Now think of cataloguing and indexing. Getting the idea yet? That's right, if every game, book etc. beginning with the word 'the' was sorted alphabetically, the list beginning 'The ...' would be unmanagable, hence they sort things like:
Witcher, The
Lord of the Rings, The

etc.

ahh now I see, I am simply used to seeing title starting with the to ignore the the when it comes to ordering, but keep it for the presentations (uggh too many thes) but this is a smart way to do it I suppose
