You know, I've been considering hosting a Hunger Games myself, after all the others that have made the rounds recently.
However, were I to do one, I'd want it to be something special; considering the fact that Hunger Games simulators have been a dime a dozen in the past month.
Here's my idea, and keep in mind that this is, as of now, hypothetical:
Everyone who takes part chooses a party of representatives, though users in themselves cannot take part.
The representatives would have to be actual, individual characters, no concepts (i.e. "Sans" and "Shaggy", not "Default Dancing Sans" and "Ultra Instinct Shaggy"). Duplicate characters are also not allowed (e.g. if someone takes Sans, nobody else can have Sans).
At the end of each day, users select highlights (not necessarily deaths) that I would then draw.
The owner of the winning district gets a drawing of their characters.
