The Maze Runner but an AU in which the Maze is Maize. Also, you get to control the main character, Thomas.
Spoilers for the 1st Maze Runner film, or book. I have only watched the film; I don't know how the book is different. But I assume they cover approximately the same events.
*The pun "The Maize Runner" is in no way original. Probably over 100,000 people have thought of it before. Many people already parodied it in videos or fanfiction. This however will be the first storygame "The Maize Runner".
