Video game which initially appears to be, and is promoted as, a cozy small-town life sim, but after about ninety minutes the town gets firebombed, all of the quirky NPCs you’ve been building relationship hearts with die, and the mechanics shift completely to a Pathologic style survival sim. If anyone complains to the developer, they simply mildly point out that it was clearly marketed as “Ghibli inspired”.
Okay, this may be just a joke, but I think if you do this right it could be an extremely poignant game! Rebuilding your community after collapse, knowing it can’t be the same but maybe it can become a home again. Comforting people who seemed strong before the event as they fall apart, helping them become whole again. Remembering those who didn’t make it. Working alongside people who were always scared (and still are!) but are now stepping up to do the work of rebuilding anyway. All the same kind of interactions you’d expect - gift giving, small tasks and requests, daily conversations, home decoration. Old friends leave. New ones arrive. Some are nice. Some are prickly. But you’re all working and living together in the same community.
You could even do the survival sim mechanics of you want, but the optimal strategy should always be building community. Help others when they fall and they’ll do the same for you.
