Yes, it's true, I can play more than one game!
This video is simply a test. This probably won't become a series.
I own only the footage in the video. The music at the end, Gaslamp Funworks, is royalty-free and originally composed by Kevin MacLeod. The game shown in the footage is published and copyrighted by Nintendo.
UPDATE: As of now, Nintendo has officially claimed copyright on the Splatoon 2 soundtrack in the video. This is a good sign, as they are not asking me to take down the video. I may make a series out of this!
