This website is a Korean website called "Watchapedia" which is a user review webstie of movies and TV shows. This website is basically based on humongous number of simple user review of each contents. Users easily can rate with 1 to 10 point system into thier watched contents, and using these big data, AI gives each user what to watch next. I think this idea is very useful and also adaptable to game industry too. How about enhancing rating system into next level and making some progress similar to "Watchapedia"?
