Maybe one of you know how to do this. I've installed Bastion on my french computer, and, well, the game installed itself in french. More precisely, it installed all the languages, but displays the french text. I'd prefer the original version. But I can't find any ini file, or in-game option, allowing to select this.

I think there is a trick consisting on adding something to the shortucut's command line. I'm not too fond of that solution. Does anyone know of another way ?

I'm playing it with the -lang en parameter. i just prefer when the game itself is set right, so that any shortcut gives the same result.

I haven't tried toying with my locale parameters around installation time. Seems a bit too much of a hassle. Anyway, i'll wait for a while, and if nobody suggests an ideal solution, I'll mark your answer as the best one.

If it is the Steam version, it can be found under "properties".

Edit: But that would probably so obvious, that is would not warrant a question.

I need to go to bed ...

Ok, this is a really old topic, so I apologize for reviving it, but I had the same problem, found this by googling and didn't like the solution presented here. Then I managed to come up with a different solution, which is still far from perfect, but at least doesn't require adding some parameter every time I launch the game. Keep in mind, I didn't get Bastion from gog, but from some humble bundle, so this might not work in gog's version. I doubt it's different though.

First of all make backups to be able to revert changes if anything bad happens:
- Save the folder "/Applications/Bastion.app/Contents/Resources/Content/Subtitles/fr" (or 'de', or 'es', or whatever language you want to change from) somewhere else
- Save the file "/Applications/Bastion.app/Contents/Resources/Content/Game/Text/HelpText.fr.xml" somewhere else

In the following I will refer to "/Applications/Bastion.app/Contents/Resources/Content" as "[Bastion]"

Now: overwrite the [Bastion]/Subtitles/fr folder with the [Bastion]/Subtitles/en folder. In the new Subtitle-folder you should have files like "Attack01.csv" and similar. All of these files have to be renamed by adding "_FR" (again, insert proper language code) right before the ".csv". So "Attack01.csv" becomes "Attack01_FR.csv". This changes all the subtitles for the narrators lines, but the menu and item descriptions still remain French (German, Spanish,...)

Therefore step two: Overwrite [Bastion]/Game/Text/HelpText.fr.xml with [Bastion]/Game/Text/HelpText.en.xml. Then open this file (the new HelpText.fr.xml) with a text editor. Right at the beginning there's a line "<HelpText lang="en">". In this line change the "en" to "fr", and save.

Done. Now everything (except for the initial text telling you, that Bastion automatically saves whenever you see the gear symbol) should be in English. I haven't played it through yet though, so there might be unforseen problems. To revert, just replace the changes with your backups.

Hope that helps other people searching for a solution to this. This really should've been an option, as someone who speaks and understands English fairly well, I find German subtitles for the English narration utterly confusing and annoying...
