I really wonder about these youtube ads for these (non-existing, AI slop) incel games... it's always the same pattern, a man is exploited and/or rejected by a woman who gets everything for free he has taken from him, is spat on and whatnot, then starts his quest to fight the demoness or whatever. Are there any articles about those and the companies behind them?

non-existing? if we mean the same ads (mainly the cartoonish knight with bluish-black hair, though I've seen a caveman variant from another game) the game does exist. I played it about ten years ago, back when their ads were still the puzzles you supposedly need an IQ of 300 to solve. (kudos for keeping up with the times, I suppose.) /s it's a gacha money-pump, but I don't think the developers are strictly guilty of false advertising: from memory, the game does include one minigame or another reproducing the ad's loop.
