Do you think, now, that you wil present games in different languages. Most of the games that are available to buy exist in most languages.
Thank you by advance.

Some games already have multiple languages included (even if the gamepage may not acknowledge it, for various reasons), others have patches available elsewhere on the net.

Look here.

One reason for languages NOT being included may be that the rights-holder to the game itself may not have the rights to the translation if it was translated by a different company.

Hmm. I think language is one of the important things GOGWiki is missing. Currently we just default the language header on the infobox to English and go by the gamecard.

So if you do come across a game that supports other languages, do make sure to edit the Wiki and note it down.

DotEmu seems to be more inclined to include different languages (besides English) to their DRM-free releases. So if the local languages are important to you, check also if DotEmu has it. That seems to increase the size of many DotEmu releases quite a lot, though.

I personally prefer my games and movies in English, or in the original language as long as there are subtitles. No dubbing for Finnish thanks, there are too few voice actors here anyway so you kinda get bored of hearing the voice of Samuli Edelmann and Antti Tuisku (for female parts, his high-pitched voice is perfect for them) every time.

Thank for all your answers. Well in fact some games are very hard about their puzzles, and sometimes one word can do the difference.. But any way, thanks to Miaghstir, for your advice. @timppu: Dotemu is very interesting but the list of games is not as good as GOG's list. Anyway, the idea and the work of dotemu is very good.
