Have you discovered 'gaming' on YouTube? It's a section devoted to gaming videos, live feeds, game titles and game channels.

https://gaming.youtube.com

The live feeds will give you a preview if you hover over the thumbnail. You can click on a game type for live feeds just for that particular game, like Battlefield 1: https://gaming.youtube.com/game/UCvh...ymyiP8ikmBhdzg
And from here you can click on 'lets play' (previously recorded live feeds) or 'reviews' (video reviews) of the game.

Give it a try and tell us what you think.
