Show stopping (Singleplayer anomalies)
From WSGFWiki
Definition
A game with show stopping singleplayer anomalies is one where enabling widescreen introduces effects that render the game unplayable at some point.
Examples
In Freelancer, enabling widescreen cuts off the top and bottom of the screen. This cuts off buttons that appear at the bottom of the screen in the planetary views between missions, making that aspect of the game unplayable.
