A game about a party of adventurers going to group therapy? It actually works as a game concept!
As you and the party continue to go on quests, it's obvious that some gripe and internal conflict will build up overtime. Being able to voice your concerns and issues in a healthy way is both soothing and helps greatly.
I like this game, as normally in other games like D&D, party conflicts are often messy and results in PvP, even if the story beat calls for it. Which often doesn't go too well. Being able to have an in game therapy session can be a great narrative point as the party sort their issues out with each other and remembering the good then the bad.
I can also see this used in other systems and settings too that calls for it.
Very simple but great idea for a narrative game that tackles internal conflict in a healthy matter, which, to me, fits the theme for this jam!
