Sadly customization and individualization are a huge content driver for most of these games. And regardless of them being “free2play” it all costs money to produce.

Most of your pay 2 play games don’t offer this huge amount of revolving customization. Even when they do offer a large amount of customization it sees an influx of individuality until the majority of the system has been attempted and then it just disappears.

Live service games end up costing loads to maintain simply in server costs so to keep up with a massive player base I can’t imagine the monthly cost that goes along with it. And that’s not even including extra content for the game itself. Itsuwari No Alice opened up about maintenance costs back in August in a bid to stay alive. It’s been eye opening when you consider the niche size of Itsuwari no Alice. https://automaton-media.com/en/news/20230803-20472/
