What are the key differences between the fast version of Monopoly and the traditional version of the game?

The key differences between the fast version of Monopoly and the traditional version are the shorter gameplay time, simplified rules, and faster pace of the game. In the fast version, players can quickly buy properties, build houses and hotels, and bankrupt opponents in a shorter amount of time compared to the traditional version, which can take several hours to complete. Additionally, the fast version may have modified rules to speed up the game and make it more dynamic and engaging for players.
