Challenging the Gods
They say the best Superman stories are the ones where the problem CAN'T be solved by Superman's powers. No amount of strength or speed can fix interpersonal drama or untangle a logical paradox. Or rather, Superman's abilities may play a key role in the ultimate solution, but they can't solve everything on their own. There's no "brute force" method. Writers for such high-powered superheroes face an eternal challenge: how to reliably put them in situations they can't just punch their way out of?
GMs face a similar in games where players can reach godlike levels of power. I'm running a Godbound campaign right now, and a big part of the fun is that many challenges that would stymie your average RPG party are a walk in the park for a pantheon of demigods. Horde of demons? Two combat rounds; three at most. Angry monarch? A single Theurgy spell makes him your best friend, permanently. Societal ills? Invest some Influence or Dominion; repeat as needed.
This is fun in moderation, just like beating up a roomful of goblins as a level 10 character can be fun. But at a certain point, running roughshod over a world that can't push back loses its luster. After all, if we wanted PURE wish-fulfillment, we'd get rid of the the rules entirely and just re-write fictional reality.
DCs don't mean nothin' when you've got the Word of Might
The "Superman solution" of non-physical challenges isn't a silver bullet (to mix our metaphors) either. Taking Godbound as an example, plenty of divine gifts and miracles can sidestep the problems one would often throw at an invincible protagonist. Even large-scale trouble, city-scale dangers, don't reliably force clever decision-making.
What are some solutions?
1. This isn't a problem
(or, wish-fulfillment can be fun)
Maybe your players just want a sandbox to mess around in. That's fine! It can't all be OSR grittiness and getting skewered by a skeleton's spear. Some groups might never get tired of putting dragons in headlocks and kicking storm giants in the nuts.
If this describes your band of herculean misfits, read no further. Let them run wild across the campaign world to their hearts' content. What I've found, though, is that this kind of license grows stale over time. Maybe a long time! But eventually.
2. Juice up the baddies
(or, ogres now have 12HD)
Godbound itself is guilty of this sin to some degree. The section on adapting monster stats advises a Hit Die scale that's quite a bit higher than old-school equivalents, and goes so far as to say that a creature should have at least 10HD if you want it to pose a challenge for the a Godbound party. It's tempting, then, to let your expectations (dragons should be a deadly challenge!) inform the power level of the foes your party faces.
Resist! This failure mode is so, so common in video games; don't let it happen to you. I've never played Skyrim, but every time I read about how if you go back to low-level dungeons at high level, all the enemies have leveled up as well, I want to tear my hair out.
If the party has the same probability of victory against an ogre that they would if you were playing B/X, then in what meaningful sense are they more powerful? If every time you get a +1 to hit, the monsters' AC improves by 1, you're treading water.
I actually do make exceptions on this point for mythical foes like dragons. Demigods vs. an ogre should be a one-sided beatdown; demigods vs. a wyrm of legend deserves an epic fight.
3. Zoom out
(or, nice empire you've got there)
Ah, domain-level play. The promised grail, so rarely reached. Unless you're a god! This is the recommended solution in Godbound--give your party vast lands to rule, besieged on all sides by dark empires and jealous rival demigods.
I've said before that scale isn't a solution on its own, but that's not entirely true. The use of Influence and Dominion in Godbound is limited by the scope of the changes you're making: town-sized, city-sized, or kingdom-sized.
Zooming out to the level of fantasy geopolitics also creates foes that can't just be killed: how do you handle a nation bent on your followers' destruction, when killing their leader just leads someone else to take up the scepter? Do you wipe them out? Is protecting your flock worth violence on that scale? Hah, ethical dilemma!
4. Go cosmic
(or, punch god in the face)
In a sense, this is the right way to use solution #2. Instead of increasing the power level of your standard monstrous menagerie, let your party fight their way up the corporate ladder of enemies all the way to the top. Broke: orcs in an abandoned castle. Woke: bound demons in an abandoned flying wizard's tower. Bespoke: insane angels in an abandoned celestial dominion.
Of course, creating epic-level adventure locations is a challenge of its own. They've got to feel strange and wondrous, not just "this is a dungeon, but you can't use your divine power to teleport through the walls because they're made of special celestial concrete." My best shot at this so far is the Oubliette.
5. Incompatible goals
(or, what color do we paint the temple walls)
You can't have your cake and eat it too. Sometimes your high priest wants to make peace with a rival religion, while the grandmaster of your paladins wants to wipe them out. Maybe the heart of a celestial machine offers the key to ultimate power, but disrupting the machine's operation would devastate the mortal world. Ain't that just the way.
go watch Over the Garden Wall
The two incompatibles might both be good, they might both be bad, or there might just be a tradeoff. The "both bad" version is a staple of superhero movies, from the exploding ferry in The Dark Knight to the death of Lois Lane in the first Christopher Reeve Superman.
But the "both good" scenario has its merits, too: imagine you plan to honor one of your followers as your greatest mortal champion, but two candidates both desperately want (or even need!) the glory.
One danger with this approach is that it risks making the characters' great power irrelevant. If I joined a campaign because I wanted to play a god of fire and death, I'm going to be pretty peeved if every session is spent debating the finer points of tithing for my cult.
So make sure the party still has a chance to open up the throttle and let rip once in a while. Put something in their path they can crush without remorse.
Perhaps an ogre?
Thoughts
One of the most striking insights of the OSR, for me, is this: don't give out abilities that render core challenges moot. In dungeon crawling this means no light cantrip, no goodberries, and no bags of holding. It got me thinking about when a game, by design, elides the classic obstacles of an RPG.
My current Godbound campaign faces all the problems described above. At level 1, the pantheon was about as capable as high-level mortal heroes, but at level 3 they're carving through krakens like cake. All the solutions listed are tricks I've tried or traps I've fallen into.
It's tough, but crucially the players seem to be having a great time.
That's the whole idea, right?
