Why people argue about this
People often think that in variants like Pairs instead of Books, you're only collecting two cards of a rank rather than four, which simplifies gameplay but can lead to quicker disputes over whether a player has enough matching ranks or not. The confusion arises because the core concept is still about collecting sets, just with fewer cards per set.
