For a minute there, it looked like the professor had no idea what game Kate was referring to. Then realization dawned on her, which Kate was grateful for, since she didn't really know enough about it to explain things any further. Kate nodded along when the professor mentioned that it was a good game to play when you didn't have anybody else to play a game with.

Having thoughts on the next question, Kate raised her hand again. "I think it's because over time, our interests change as the world around us changes. For example, muggles have had lots of development in technology over time, so a lot of their games have moved to computers or other systems that use technology," she said. "I also think it's because we make improvements over time, and everything becomes bigger, better, and faster."

Or safer..., like some of the broom-related games.
