I'm there for the added layer of humor provided by the "reactor." Like GameGrumps. I am not watching them play games to see them play games; they actually kinda suck at most games and its frustrating seeing them unable to solve easy puzzles or win easy fights. But they are funny as fuck.
Idk if watching someone play a game counts as a "reaction" video. In my mind a reaction video is a video that shows someone watching a YouTube video that you probably don't even get to see unless you go watch that video on your own.
They are generally reacting to games they have not previously played for fun so you get their genuine first impressions. Not always, but a very good chunk of the time. Especially the one-offs and not the long-plays.
That's a fair take, I'm just not sure that's what op means. Perhaps I am wrong. My mind just files gaming videos separately from "reaction videos", I think because the gamer is actively taking part in the game, rather than reacting to what someone else has already recorded and posted.
If the gamer is just watching someone else play a game and reacting to that, then it would fall into my idea of a reaction video.
I think some of y'all need to learn how to parse a paragraph. I am not saying Game Grumps is a reaction channel, I am saying I am there for the commentary and humor, the same as with reaction channels.
It's just a video with a silent face super-imposed over it and nothing else.
Also: You don't even seem to understand what an actual reaction channel is if that's what you think they are. Either that, or y'all be seeing some of the worst, bottom of the barrel "reaction" content possible.
