One very large video game studio has tons of automation for Jira. Imagine someone deciding to add new weapon. The automation creates 100s of tasks for concept artists, 3d artists, animators, sound artists, software developers with complex dependencies better those. Most importantly, automation creates multiple QA steps for each element of completed work.
The same exists for levels, enemies, quests and tons of other elements.
I would not be surprised if a lot of studios had similar workflows.
