Advertising for games has been a hot mess for decades.
Mobile games, making a paralel here as most of the games here are supposed to be mobile,
have majorly disingenuous advertising most of the times.
Pitting the whole game on some minute small portion of it, the part that gets advertised,
which so many times turns out to be only fan service or trivia short segments,
will blow upin their faces the minute when players get into the game, as they will
quickly find out the sour truth that the meat of the game is not the advertised story,
it might not be the renders either, maybe not the angles shown in the previews,
so of course they get pissed and this is supposed to show in reviews and in the ratings.
The rating system is pretty meaningless anyways imo. The 5 star ratings are just as ridiculous as the 1 star ones. People, most of the time, don't go by objectivity, they go by emotion. Like, man, "Cindy" from "Harem house madness" is so hot + the lewd scenes are fucking dope dude, believe me dude... #Cindy4life. Well, that's an easy 5 fucking stars, ain't it?. Or the other way around, the game has outstanding renders, music, writing, story, animations, pacing, but there's a forced femdom scene... 1 star, no questions asked..
Many games make a mock of their plot and their game mechanics when they put in the overview or the tags,
so gamers who find most of those elements will rate it high, while gamers who will not,
believe me some games make it especially hard to find the selling points of the advertised games,
so gamers missing the whole mark will rate them poorly.
These are the same reactions that are going around over on Steam or on It ch io,
as most devs who lie or deceive or few words about their games will get lambasted.
