You need to go back and fix the timeline.
Good luck.
Gacha games, and stuff like Farmville (which I'll call "social games"), are much more insidious than that. It's not about one skin, it's about harboring an ecosystem where players feel compelled to have all of the best stuff so they can either compete or just keep up with others. Such games aren't actually designed for average users--they're microtargetting that tiny percentage of players that are psychologically vulnerable to addictive game design. These games are actually lures for whales, which is where (IIRC) the vast majority of their revenue comes from.
It's exploitative and wrong. However you feel about the people participating in playing, the companies involved know exactly what they're doing.
