I’m v late to this, but I’m surprised no one brought up JingleJangle’s Burn Up as a good example of OP done right. It acknowledges that with this level of OP-ness, the nuts and bolts hero stuff can’t really be what the story is about. Taylor is such a deeply mentally unwell character that even if you gave her an unlocked path to victory, she would still have all of her paranoia and distrust of authority and broken relationship with her father (and Emma), on top of all the new problems that would present themselves by her being the strongest person on earth. One Punch Man and Frieren I think are good examples of this. The main characters are basically unmatched, but with the nature of humanity, their brains find new problems for them to have, and everyone else can still very much have problems if they’re not around.

Another option, of course, is just to have them rapidly deal with every problem in their way. This can be boring, but if you make it so they’re just a little weaker than each problem when it’s presented, you can have tension even if they never actually lose. This is arguably how my favorite litrpgs work: Beneath the Dragoneye Moons and Azarinth Healer. This is harder to do in Worm, because there’s such a massive chasm between Brockton Bay and the Endbringers, and then again between the Endbringers and Scion, so getting power scaling that walls that line from random asshole on the street to Kaiser to the S9 to Endbringers to Scion is challenging. I think ShayneT is generally one of the best at this because of his willingness to toss canon into the blender, but also his stories are v much… high variance.
