For what is worth, here are my thoughts on this, I call this idea the "story tree":
What I thought we needed for quite some time is a new "Story" section in the codex, where the quests are displayed as a tree, so one can clearly see how the quests depend on each other. New players can then look up what they need to do to progress and have a better understanding of how everything is connected. It also helps us to look back at old content, also in case we want to replay it. And it would be a good interface where to place tutorials, and remind us what was unlocked by each quest.
Then, once you have the story tree, I think it would become easier to implement a pay to skip, where you can pay plat to move up to the next quest. Some quests are themselves tutorials, so choosing to skip would probably be best if implemented on a per-quest basis. If you skip the quest, perhaps you can have a shorter new tutorial in there, and later on come back and play the quest, which would be marked as "not yet played" on the story tree.
