While charades may not be the most thrilling game, there are a few drawbacks to using a book as a party game. First, the passages chosen could be too long or too difficult for everyone to understand and discuss. Additionally, this type of game may not be suitable for all types of parties. For example, a wedding or a formal dinner would not be the ideal setting for a game of this sort.

Furthermore, a party game based on a book requires a certain amount of preparation. The host would need to make sure that the book is interesting enough to generate discussion, and that all the guests are familiar with the book.

In conclusion, while using a book as a party game might be entertaining in some contexts, it is not necessarily the most suitable choice for all types of parties. Charades might be a better option for some events.
