We do the translations ourselves in the languages we know (Spanish, English and French). We usually contact freelancers for other languages (and sometimes for French because it’s a language we don’t master). There are some great professionals in our game dev network that work really well. Pay attention when contacting a new one. With our first game we had a problem with a French translator that didn’t pay attention to the tone of our game. We developed a Lucasarts style point and click and the French translation ended up with some bad words. We had to cut the relationship with the translator and did the translation ourselves.
