NFTs in blockchain gaming ecosystems significantly influence user retention and spending behavior. By enabling true ownership of digital assets, NFTs create emotional and financial investment, fostering loyalty and encouraging prolonged engagement. Players are more likely to stay in games where their assets hold real-world value or status, enhancing retention rates. Moreover, NFTs drive spending as users purchase unique items, skins, or characters to gain competitive advantages or social prestige. Scarcity and exclusivity of NFTs further incentivize spending, as players seek rare collectibles. However, high entry costs or speculative markets can deter new users, impacting retention negatively. Balancing accessibility and value is key to sustaining user engagement and spending.
