It allows players to collect daily production revenue based on **the unclaimed $SITY balance accumulated in their NFT**. This shift encourages players to strategically manage their resources and claim timings to maximize their daily Factory bonus. Upgrading the Factory increases the percentage of daily revenue that can be collected. This building remains essential for boosting your passive income and driving the growth of your city’s industrial sector.
