Some people don't accept gacha otome games, but the genre is genuinely huge, and that doesn't make it inferior. There's nothing wrong with spending money on gacha games, either. In fact, a lot of gacha games are really high quality. The mainstream buy-to-play otome games are made by Otomate, and their stories aren't necessarily all that great. When it comes to sexy content, Chinese gacha games definitely can't go too far, but gameplay-wise, gacha games are more fun. The exception is Koei's otome games—though even Koei has jumped into gacha, which proves gacha is what capital and the market have chosen. Ordinary buy-to-play otome games don't get much investment, and the ones that did get big investment never went anywhere—like Capcom's Toraware no Palm series and Konami's Girl's Side. One good thing about gacha games is that you can openly play for free and no one gives you crap, whereas with buy-to-play games, if you don't pay, people will accuse you of freeloading or buying pirated copies.
