See, I’ve always envisioned an out-of-the-norm final confrontation in a hypothetical video game as being in this large vacation home in a beautiful mountain town (kind of inspired by the Adirondacks). The town would otherwise be peaceful. A sort of melancholy but beautiful music would play in the town.
There’d be no enemies except for the principal antagonist, and I’d imagine the confrontation mostly taking place through dialogue. Maybe that’s be appropriate to the genre and maybe it wouldn’t, but it’s sort of how I’d want my dream video game to conclude.
