Cyberconnect2's passion project has never gotten as much attention as it should in the west. I played it, originally, because I was looking for something to play. I immediately was sent down the rabbit hole of the Little Tail Bronx series. Got my hands on a way to play Tail Concerto and the DS game, and the amount of love and care put into this series is staggering. Coming across archives of their artbooks alone is like uncovering treasure. I don't even understand the Japanese text, but by what can be gleaned of the images the amount of world building is staggering.
I just wish that I had more ways as a westerner to support this niche series.
