My Root box is quite big, because it’s the french edition so it includes the Root automatons, and the first expansion (Lizards and Otters).
I think the smallest box i have is Complots which is a french version of Coup, with squared cards, it fits in one hand.
It definitely looks different and bigger. Jealous! I have to use 3 boxes to fit everything XD
Haha yeah, I still had to buy new boxes for the Underworld and Partisans expansions, but at least it only three of those !
