When I think about what “casual” means, I usually envision a T-shirt with some silly pop-culture phrase emblazoned on the front or a nice family restaurant where little geeks standing up on the chairs is considered standard practice. When we consider the term in the context of games, things start to get a little cloudy. The opposite of “casual” is “formal”, but this makes zero sense in the world of tabletop games. You don’t, for example, play games formally, in business attire, in a corporate jet. Although, that would be pretty cool.
