I'd like to see something which explores the post-adventure celebrity. You've come back as a group from some grand adventure which has made you fame but not fortune. Now you're having to adjust to this famed lifestyle as a group.
Being summoned by nobility to lend your new found popularity and imagined coin.
Getting mobbed by people wherever you go.
Trying to continue making a living as adventurers when everyone recognises you and gets in the way.
Could be interesting
You know, I was half expecting people to troll and suggest something like "Made in Abyss".
