Shitty gacha games print money like it's going outta style, and I doubt any of us would consider those among the best games we ever played.
Not trying to argue with this much, but as a person who played a lot of gacha games, it's kind of interesting to see parallels between those and CoC/TiTs.
Both CoC and various gachas are essentially about one thing - the characters. Gacha Games spend enormous resources to write, design, voice act and animate a perfect character that will someone to gamble just to get them, as well as enormous amount of fan-art and porn. And it culminates in shit like story events, where gachas give you entire visual novels just to sell you on this character. But naturally, not all of them are nearly as popular and every gacha has at least a few characters that are 100% forgotten by the devs.
Fenoxo games, essentially, are doing the same thing, except it's even more unstable due to several reasons, mostly understandable. The biggest problem is that, due to being less professional, the problem doesn't end with just characters being forgotten. It ends with clearly seen bias, where some characters are clearly more liked by the devs than the others and there isn't a clear end plan for some of the others ones.
Even gachas often do stuff a bit better, simply because they have a clear focus on who the character is and what content they are a part of. To be fair, it's not like gachas go too deep with the relationship systems (it's literally just a few voice lines by the character most of the time), but I wonder if Fenoxo games just throw some random OCs they made into the game with no clear plans for their actual development and, being a porn-game with all sorts of content, gives an idea that those characters were meant to have something, but they actually don't.
