This was a pretty dumb read. Lots of things just slightly wrong and mostly complaining.
First of all game reviews have always been about finding a core that you can connect with your audience about as with all reviews. Maybe its the game genre, it maybe it is a style or an emotion you have at your core.
And to that there are new trusted reviewers all the time, you just aren't personally hearing about them.
A new one that has gained following is IronPineapple who set their core to darksouls like games but because of their willingness to flub the definition a bit they have character and people have flocked to them for trusted takes about skill based games.
RyeGames is becoming a trusted voice in acting as a living games historian.
No new reviewers? Bullshit.
The one thing I agree on is how useful steam reviews are. Yes or no and show the percents and see what people said. Almost always there is a synopsis review and a more emotional review to tell you if its for you or not.
