I think writing IF is hard, and translation is hard on top of that. Is there a big IF translation award? Perhaps the languages and audiences are too scattered for that.
I think/hope people here would be very open to a call for testing/reading a translated work. While my writing was in English, I relied heavily on testers for typo detection and other issues because I just don’t have the attention span for adequate proofreading. My game would have been a complete mess without their help.
