Long Form Game Retrospectives

Hi there, I am in the midst of building my first YouTube channel. I would like to make game retrospectives. A clear example of the videos I'd like to do is the following channel: https://www.youtube.com/@TheSaltFactory

I want the editing to be straight-forward. Very few bits of humor, which means most of the video will be chopping and syncing what I say with the footage. For intros it will need more work since I want to make a story around how I got to play each game, so there will be a bit more work there, but for the most part it's chopping footage. I want to make it look professional, just like SaltFactory.
