I was looking through some of the categories and saw that the staff credits were absent. Was this left out on purpose or by accident?

are you talking about the credits after a full game run not being shown in the vod or video of a run?

More like an individual run trying to get a high score on the credits

literally no one cares about that. and also it isnt a speedrun, its trying to get a high score, so its not on the boards.

Makes sense
