It’s a strength that we developers have mastered over the years, employing it in various ways to different projects. As our games grow more sophisticated, we will continue use it for more subtle and powerful emotional triggers. I think we should always be searching for more ways to add releasable tension to our projects.
It’s obvious when titles lack a good balance between tension and release — players feel it internally. We crave tension on every level, and we find joy in overcoming it. Exposing this delight to players is an indispensable way to hook them and make our games more successful.
