Revisit Old Games Option
I have played many games where the tension gets heated. The stress runs high and one player surrenders impulsively.
Game over.
It would be nice if the people who played the game could all decide together that yes, for statistical purposes X team is out, but the game continues, for fun only. Works perfectly in two player games.
It would require perhaps a 'revisit old game' option. Like play it again dude.
It would encourage community building as people would start wanting to talk to one another.
It would encourage people to play their games better as they can actually see what would happen if they played well.
A time limit could be imposed... so like 5 minutes to decide if you want to play it again. Then it's gone.
