Forum:Should some info from the Baldurs Gate games be canon?

I am a huge fan of the Baldurs Gate games, and a lot of my knowledge of Faerun comes from these games.

I appreciate how the layout of towns and playable scenarios should not be treated as canon but...

Within the game we are told many pieces of information, e.g. you can ask characters about the area, you can even read books within the game.

What i'm suggesting is that we allow some in-game information to be considered canon. Information I would like to be considered canon;
 * In-game biographies
 * In-game readbale books
 * Information told to us by in-game characters.

What really made me think of this is the vast amount we learn about the story of Durlag Trollkiller, but seeing as he barely appears in any other literature, the wiki page can hardly confirm any information about him.
