I have no desire to bash the show in terms of production value, presentation, quality etc. I'm also unfamiliar with his previous work elsewhere.
At the topic at hand, though, I felt the argument was lacking. For one, this would be a sound argument well over a decade ago, as a heads-up when technology boomed and video games were changing their form and presentation. Now... it's coming too late to the party just to get drunk and dance naked in somebody's face.
Secondly, this is a position I don't necessarily agree with, but maybe I could see the point made, if the argument was complete. I'm not the biggest fan of Extra Credits either, but at least those guys go to lengths to establish their arguments, via examples and/or suggestions. This was venting... which is fine when it's funny, but not-so-fine in any other case.
Thirdly, what did come up finds me disagreeing for many reasons. For starters, videogames are and always will be comparable to movies in one way or another, because they share one thing: they are both visual mediums for telling a story. Granted, the presentation is different and you can argue that not all games are about telling stories; which is true. However, unless anybody suggests we completely eliminate story-driven games, the point is moot. Considering their connection, it's not only unlikely, but also not advisable to completely separate films and games. Certain games in particular and gaming in general have only to gain from keeping an eye out on movies, without that meaning they have to follow in their shoes or try to be like them.
Not to mention, the idea of something cinematic is a development, an evolution of video games. You couldn't sit people down and make them read dialogue box after dialogue box for ten minutes, while the sprites just moved half an inch every now and then back in the so-called "golden" days.
Seriously, I know many don't care for Metal Gear Solid, but those who like the series even a little bit, can you imagine it any other way?
I will give him this, though. His intention is noble, insofar as praising games as "cinematic" and "Hollywood-level" goes. There is a condescending side to this argument whenever it's brought up and ironically, it hurts games like Heavy Rain and Fahrenheit the most; mainly because these are exactly the kind of games that do not need to promoted as such, considering they rely on interactivity. Cutscenes in Metal Gear Solid or Devil May Cry are there to either tell the story or set the mood. What sets the mood in Fahrenheit is the interactivity. Everything else is the salad dressing; important salad dressing, but dressing nonetheless. So, at least as far as that goes, he has a point. It's just the idea that games should be removed from movies that I find false.
