Unfortunately, this
, is the only video that I was able to find that matches most of your description, but not entirely. I've looked through about 20 or so videos and this is the closest that I could find.
I'll have to give up on this for now, sorry.
I was very curious with how Half-Life would of figured into all this. Haven't been able to find even a single video that matched a Top 6 or Tier List and talk about Gordon as well. Personally, I've not discounted the possibility that this particular video wasn't 1/2 part of a written article somewhere. And, well, being unfamiliar with Smash Bros doesn't help me particularly — I've had to filter search discounting mods, costumes and hypothetical character proposals and implementations.
For whoever is going to pick up the thread, good luck!

I'm looking for a Youtube video that explains the creator's most wanted characters for Super Smash Bros Ultimate. In the first pick, he explains that he likes how the series represents different consoles like Sega, Playstation, Neo Geo and that we haven't got a PC rep yet. He chose Valve and from the studio came Gordon Freeman from Half-Life.
