Hello and welcome!
A Spanish translation would be great! The next step is to just translate the strings. I will send you a file via email. It’s quite a lot and you can also start with a lite version that translates only names of buildings and resources.
With the translations we have so far, I did the technical part and sent versions back for testing. So people don’t have to deal with the modkit. But you can also compile it yourself of course.
See you in email
