Yeah, I get that. I still watch people like TotalBiscuit though, even if he's more interested in game mechanics and the technical PC technobabble and I'm more interested in story. If a game is objectively bad, I'll know from listening to his critique, and I'll also know if it's worth my time researching it further.
Well, there's a YT reviewer channel (joueurdugrenier) that I follows, if a game doesn't make it there it might be not so bad 
But well, he's doing really bottom line.
Edit: when will the embargo got lifted? Anyone got any informatioN?
yea even if you have a certain YT-ber that you follow and he/she is more interested in the mechanics and/or tactical viewpoint of the game I still say try it for your self, and see if *YOU* LIKE IT ! Because as I said, there are different opinions there weather is story based or not, you cannot be sure until u get your hands on it, and if you don't like it... then that might be a waste of you money... but if you *DO* than thats an "investment" in my eyes.
Ive tried a lot of different games based on YT-bers reviews and a lot of them I can say I didn't like that much .. so it all depends on how *YOU* FEEL about it if the story emerges for you or not...
