I don't believe that the trilogies are as deep a departure from any% enough to be their own category, especially not a main category. However, for those not as interested in doing the whole game in one sitting (It can be daunting if you haven't built the stamina for it), the game does have the super stories that are an easily learned and ran category on their own.

It’s a thought

We use in-game time for the glitchless category anyways, so your timer matters very little...
