The month kicked off with 9yo deciding to make his own "card game" after ages of playing Magic and Yu-Gi-Oh. After quick playtests with me and 11yo, 11yo decided to help make even more "cards". I use the term loosely bcause the "cards" were all A4-sized.
The game was fairly simple and entertaining, and after playing a couple of times 9yo decided that he probably needed more "good" cards as it didn't take very long for me to die despite the lives and death prevention things that had been added in the iteration with 11yo.
