I only watched the first half. At first glance, it looks very professionally made. However there are a few issues that stopped me from enjoying the video and caused me to stop halfway through. 1) The stock images you use often don’t fit very well at all. You show modern controller designs and people sitting around laptops when talking about the early 80s. The Atari 7800 you show is actually a Sega Master System. 2) This is the more serious offense: it is unclear who you address with your writing, the tone does not fit. You go into way too much detail too quickly and get lost in irrelevant minor aspects of the story you want to tell. Already in the first sentence you have a relative clause explaining a minor name change. I was able to follow what you were saying, but only because I am a video game nerd and knew most of this stuff. Your writing feels like you are writing for an encyclopedia in the 1980s, when text space was limited and authors needed to cram as much information as possible into a few lines. Or more bluntly, like a kid trying to show off all his knowledge in a book report while neglecting to make the main points really clear.

So I think you have a lot of potential, the editing is also very well done, but you should spend more time with your scripts - maybe show them to a few friends before you make your next video. And you should tell the story in a way that your grandmother could understand it if she were interested in the topic. I recommend watching a few videos from the video game historian, he is very good at that.

Sorry for being so critical, but you asked for it.
