I'll be blunt with you. Callung the guide file A_Tour Information.TXT does not sound like it has any relevance to gameplay. Most people wouldn't even look at a TXT file that literally said gameplay guide. This is a case of dev perspective vs casual player perspective. It's when a dev does something that he believes is obvious since he made the game rather than trying to look at it as a casual player. A game dev had to add a large section as a tutorial after getting lots of comments complaining that they couldn't get past the first obstacle, simply because the game had nothing to explain how the game works.
