In a new YouTube video detailing game design pitfalls that regularly derail game development projects, Fallout co-creator and veteran RPG designer Tim Cain said one of the most common issues in game design stems from neglecting an overlooked skill: Knowing when to stop.

"As a very wise designer once told me, 'A game that includes everything is about nothing,'" said Cain, who recently returned from "semi-retirement" to resume full-time work at Obsidian.
