Is this game in multilanguage? Is it english only or also italian, spanish, or franch?

I have this game on Xbox and I love it. I want to buy it on PC as well but I don't want to spare the German dubbing (which is really great, featuring Bart Simpson's German voice!). So is there a way to play the GOG version in German, either native or using some kind of language pack, or am I better off buying the Steam version?

The gog version is only in english. I don't know if there are unofficial translations.

Hello,
But it's strange, in the folder of Psychonauts (WorkResource) there are a Localization folder and more languages available (French, Spanish...).
Anybody knows how to activate it?

I'd be interested to know too. Now, there's a promo on Steam with Psychonauts at only $2... They mention the game has several languages available.
But i'd prefer to buy it from GOG, frankly, and to know I could play it in my mother tongue would definitely be a plus.

Hello
In fact, it's really simple :
Thx Miaghstir, see this post
http://www.gog.com/en/forum/general/list_of_multilingual_games/perm=1/#p_b_1
or simply do that :
Psychonauts
* English, French, German, "Nonsense" (1337-like)
* Italian and Spanish are present as folders, but contain no language files, so they make no difference
* Go into the <game>\WorkResource\Localization folder and make a copy of "English" then copy the contents of the language folder you want to use, paste it into "English" (the original, not the copy) replacing files when asked to.
* Only changes text
Good luck
