oh, haha yeah it's confusing.
but it goes roughly:
gen 1:
- ochitsubaki
- amadeus
- liar lioness
gen 2:
- yuzu/haru
- inviolet/sacrosanct
- feverfew
gen 3:
- yuui/hotaru
- suzu/haruie
- yue xianming/qian zhouyu
gen 4:
- cynosure/cormorant
and that should be the main order for the most important games going chronologically! good luck haha!! I think it's cool you're trying to play all of them, feel free to dm me on discord @ swanchime if u have any thoughts or questions 🍈
