Hi,
just wondering if Xenonauts will be available in any languages other than english? It seems that you have a very active and helpful community, so you might get lots of free translations from your users...
I personally don't care (prefer english), but I know a lot of people that wouldn't play a game if it isn't available in their native language.
I'm involved in an open source project called MediaPortal where we also get our translations from the community, and we recently started using an online translation tool for it (https://www.transifex.net). It really helps with managing translations from many different sources. There's a couple of alternatives as well (I've also used mygengo.com), but imo transiflex is the best option currently available.
