Personally, integrating lightning into games helps to get people to keep playing the games. Sat rewards act as a great incentive. I personally love ThndrGames' approach to bitcoin gaming. Their users play games and earn sats and they have an awesome referral program that encourages these users to get their friends to download the games and play them too. The referral program gives the users an added opportunity to earn more sats as they refer.

On the game development side, Zebedee has made it easy for game developers to integrate lightning into their games. According to an article I read by Zebedee, this integration has helped some of their partners experience a significant increase in app downloads.

I hope this answers your question @SatSqueezer.
