I’ve finally gotten back into playing games with my older kids, essentially because I am no longer so absolutely eviscerated from a day with the twins that I have the energy to do so. And this is coming from someone who literally went to school to learn to teach others. In practice, I really hate learning to play new games or teaching others to play them.
In theory, I enjoy playing board games and card games. Are you looking for easy card games for kids and adults? Games that you can be up and playing in minutes without slogging through a novel-length instruction manual? Games with quick rounds so nobody is getting bored and everyone is engaged? SAME.
