Thanks for your encouraging words! In fact each of IDV, MDZS and Genshin have multiple fan games here, and that's why I noticed the games in the first place. Judging from the number, Genshin seems to be liked among western gamers?
And I agree that bara games are more popular here xD there are tons of bara/furry/bara plus furry games on itch, that's probably because the gay audience's more interested in those kinds of games... But Japanese kimonos are to the liking of many people as well, so I guess it's not just about muscles. Maybe the art style isn't...idk, manly enough??? Besides that, Asian clothing can show muscles too, like this game I recently played called NU:carnival...the characters' clothes have exposed skin here and there, and even have their suits torn during battles...
Another thing, I don't know if anyone mentioned this before, but your art style seems more western than eastern. Your western games' art just look more appropriate, although I don't really know the reason...
As for the fan communities...we couldn't really get access to most foreign websites like Twitter and Reddit due to region restrictions (yeah, China), and itch is one of the few sites on which I can directly communicate with ppl from other cultures. If I make games solely in Chinese, I could just post them in Chinese websites, there's certainly more people who understands the language there - unless the game has some 'unmentionable' contents, if you know what I mean. Itch is an international platform, which is more open and more...free, especially on LGBT topics, I love the discussions here. So if I am to put games on itch, maybe I would first finish it in Chinese (just because it's easier writing in your mother language lmao), then translate it into English.
