The way this game is played is by creating a category in which the next player names an example which they think is most typical, standard, or quintessential for the previously named category. That player then creates their own new category which the next player responds to and so on. The category can be literally anything for which there are multiple examples to draw from.
For example:
Player 1: PC’s of the 1980’s
Player 2: Commodore 64!
Next - 19th Century US Presidents
Player 3: Benjamin Harrison!
Next: Hanna Barbara cartoons
and so on.
I actually like that last one, so the first category is:
Hannah Barbara cartoons
