Why is only available English as language for many games ???????

Many times I believe this has to do with game rights. GOG may not get the rights to release the games in other languages. As well, some game may only have English available from the source GOG uses.

...Because most of the games were made in the U.S.A.?

Because world domination.

A lot of them were probably produced by independent contractors that might still have rights to the translations.

I'll trade you one of my English only games for a good Settlers url that isn't only in German. :P

no. i've got the original Theme Hospital in Italian , English and others

cause politics.

And I think English is the second most widely used language on the planet.

Although i dont speak much of any other language than english I would like to see developers and rights holders etc make more languages available for their users. While some older games will likely never get additional language support in an official form it is something i would like to see more of in the future, however then it adds to production costs etc so it will likely never really happen.

That's not a problem at all, in fact I can give you at least two sites:
http://www.settlerek.prv.pl/
http://settlers-forum.prv.pl/

I can promise that bothh fulfill your requirements :D:D:D:D:D Am I evil or am I evil?

Well I was gonna say this:

"OK why complain about the game being english only when you seem capable of writing english?"

But than again there is Google Translate or you already know some words.

Licensing.

Also English rules bro.

Smart ass. XD

Can we get duke nukem Manhattan project in Latin please?

Preferably the pig kind.
