Questionable Questing

In this way, the Danmachi gods are actually rather kind and morally righteous in how they treat their familia, but for protagonist-Biigoh, maybe there's like two tiers; cute collectible characters like kinomoto sakura who are put in familia category, and randoms/losers/trash who are put in the player category. In this way, you have pets cute girls and slaves workers

I guess you're right in that even if we reduced the number of characters and actions at the start, it's still really complex and needs more streamlining.

Maybe we can work backwards? Start with a small light dimension in marvel, get kicked out by OAA, pick up random pieces of trash in the space between worlds such as twilight lance (dxd), idea of evil (berserk), and yggdrasil seeds (fgo)

In this way, there's actually three perspectives this story can be told from, the MC, the Pet cute girls, and the Slave players. Perhaps the big point of conflict for the MC would be that while nighomnipotent in the light dimension, outside, just a powerful mage. Need to learn to invade worlds, maybe. The other two would be a Danmachi-like POV and a Terror Infinity-like POV

Marvel dimensional lords try to influence the real world and take it into their own realms, or something like that, so MC can directly or using players to create positive alternate realities of worlds she finds that she can absorb into the light dimension. So players have quests; if everything turned nuclear apocalypse, yeah it's new world, but MC don't want it.
