Or you can go the Translation Wizard(TM by Neji) to translate faster with more texts involved and also "module-wise".
Translation Wizard? a translation program? Please, i beg you not to use them, not only in spanish, in any language. Their translations are pathetic. Let's see two examples:
Spanish sentence:
El gato está comiendo patatas, pescado y carne, lo que significa que es omnívoro
Real translation:
The cat is eating potatoes, fish and meat, which means that he's omnivorous
Translation Wizard translation:
The cat is beginning chips fish and beef i what significa what is omnivoro
Another one, this time in english:
I beg you not to use them
Real translation:
Te ruego/suplico que no los uses
Translation Wizard translation:
Io rogar usted not to use them (belive me, that's not spanish, that's not even a language)
Please, if you don't want me to help, no problem, but that's and incredible game that deserves the best translation possible to all the available languages. By the way, the translation method that you said looks very easy to do
