Hey we have a small web project with a team of mine that concerns this matter (To be able to filter Streams/Games) to the very core. We have a set of detault genres/themes on: https://shikenso.com/?tab=1

Yet to get more Data on the streams - a streamer need to register and upload his schedule and set tags to his schedule/streams. Once a user for example uploads a schedule for an indie game and even tags it with "speedrun" "indie" etc. poeple can filter them out in our calendar. We are still a startup so obviously we still lack the data and have to make the community aware of these features.

Feedback and innovative ideas on this matter appreciated!
