Well, you have to take into account that in Spain most people don't understand more than really basic English. A nerd into geeky things like me could be an exception, but in the end, I speak decently because I started to learn the language at 6 (my parents made the effort to send me to private class). A lot of people navigate through English classes at secondary and high school with no real grasp of the language, and they manage to get the pass somehow. Even universities only ask for B2 level.
It's not really a bilingual country, I don't know about Latin America (but I'd guess in some countries like Argentina people care more for English). So, translating from English is not stupid for people who don't understand Japanese and don't care to learn it. And like I said there's a strong need for videogames translated into Spanish, let alone VNs.
