Some collaborates and I have a little side project called JAMTANK. We try to complete new creative projects from start to finish within a month (in any spare time we can find).
Anyway, in December we designed and printed a very simple card game. It's a creative social game in the style of Cards Against Humanity, designed for 3-8 players.
Players design questions according to certain constraints, and then take turn answering. Creativity is required at both stages. The game can play out according to the mood of the group. It all depends how you choose to create the questions.
We have a web version on Alex's site.
