Hello Itch Team!
I don't know if it's technically feasible for you, but you really do a great work here with this marketplace, so I believe it might be worthy taking a look at this since this change could open many possibilities for every developer who publishes through Itch.io.
I'm planning to translate my current project to my mother language. I'll create another page for the other language version and also translate the game title instead of sticking only to one page with a single title.
It's the same principle of AAA games like Mega Man/ロックマン and Castlevania/悪魔城ドラキュラ. Mega Man and Castlevania are titles which makes much more sense for us westerns, while ロックマン and 悪魔城ドラキュラ are instantly recognized in Japan.
To create two pages for each language is easy through Itch.io, but our accounts are bind either to USD or to BRL, We can't have both at the same time. Many folks here can't afford to pay in dollar (even through Paypal) and if we could offer games in BRL and other currencies (which Itch.io already support) we could make a more solid marketing strategy for more languages and regions.
I strongly believe that everyone, both players and developers, would benefit a lot from this change.
Thanks for your time and best wishes!
