I like watching Overwatch and Rocket League footage. But this only applies if you're somewhat competent at the game, and also I find gameplays of A Story About My Uncle strangely soothing and I love just watching it so you can try that out as well! Also even if you dont want to make a video about it, I strongly recommend A Story About My Uncle because that game's awesome and it's got a great storyline with graphics that makes you feel relaxed!
