Q. How to tell when a game page is overwaught?

I'm typing up the page for Organ Trail: Director's Cut in a Word document, and I found myself going into a lot of detail regarding the functions of each game screen, since half of the game is text menu. I feel like I'm writing a guide or a user's manual instead of a proper explanation. I'm up for providing detailed information, but where should one stop before they have a huge wall of text? What should be avoided?

Wiki pages should just give an overview of a game, you shouldn't be going into minutia. So, you should be briefly outlining each game screen, at most.

Sounds good to me.
