8 Board Game Expansions That Improved on the Base Game by Every Measure

4. Splendor: Cities of Splendor - Jewels of Innovation

Marc André's Splendor was already a masterclass in elegant engine building, but Cities of Splendor proved that even the most refined designs could benefit from thoughtful expansion. This modular expansion addressed several subtle issues with the base game: the occasional lack of variety in gameplay paths, limited player interaction, and the potential for experienced players to fall into optimal strategy patterns. The expansion introduced four distinct modules that could be used separately or in combination, each addressing different aspects of the game experience. The Cities module added location cards that provided alternative victory conditions and encouraged players to diversify their gem acquisition strategies, while the Trading Posts module introduced special abilities that created unique player powers and asymmetric gameplay. The Orient module brought new noble cards and mechanics that increased the importance of timing and resource management, while the Strongholds module added a spatial element that encouraged more direct player competition. Each module maintained Splendor's signature accessibility while adding meaningful strategic depth, ensuring that the game remained easy to learn but offered increased replay value and tactical variety. The modular nature of the expansion was particularly brilliant, allowing players to customize their experience based on their preferences and gradually introduce new elements as they became comfortable with each addition. Cities of Splendor demonstrated that expansion design could be both comprehensive and flexible, providing multiple pathways to enhance the base game experience.
