Unpopular opinion: Continuing to target Pokemon and Sonic at elementary-school-aged children and completely ignoring what any adult wants is the correct thing to do.
Also unpopular opinion in some circles: COD's approach to multiplayer--fast TTK, privileging positioning, team coordination, & loadout effectiveness over acrobatics--was generally a good thing, and players complaining that they are "good" but keep losing to "bad" players do not understand what "good" and "bad" mean.
Considering how the opposite of your first point can turn out, i.e. the current state of Magic: The Gathering today, maybe there is a point to that...
And regarding your second point, Battlefield fans seem to find that opinion really offensive for some reason. Then again, given that Battlefield 2042 was utter garbage, I don't know if those said BF fans still get angry that people like COD's gameplay better.
Going back to the topic itself, I never understood the idea that "you have to play the game, before you can make an opinion of it" ideal that some people have. It seemed to have came up A LOT with The Last of Us Part II, with all of the TLOU2 Stans using that, "you don't understand the story, and you need to play the game to understand it," as an argument as to why the game is "The Best Game Humanity has Ever Made", and "it has 300+ Awards for a reason".
I also find watching livestreams of games, despite the negative factor of streamer culture, to be very useful, in deciding whether to buy a game or not, given today's trends of "Subverting Expectations", and "We'll Fix It Later by making our game a Live Service".
And seeing videos like this, still makes me wonder how Valve gets away with a lot of things, that other game companies would get absolutely ass-fucked if they were to do the same.
