I noticed that a few runs for the PC version never have a cutscene show up that needs to be skipped. Why is this the case? Reason I bring this up is that I don't think this should be allowed. I run on the actual disc so I have to skip custcenes.

I run on disk as well the only requirements for a run are erasing all progress before starting a run. Cutscenes are skippable so we allow it because it just makes the run faster. Now some cutscenes might just be skipped super well and hardly pop up due to fast load times.

I highly doubt that every cutscene is skipped instantly, but I'm not gonna make a scene. In any case, the version available on this site does not play cutscenes ever, and so provides an unfair advantage to those on disc. A tiny, tiny disadvantage, but a disadvantage nonetheless.
