In most cases, you will be able to select the game language before downloading starts. In the window that appears right after clicking INSTALL.
If this was not possible, or if you have already installed the game, select it from the list on the left-side of Galaxy, and click on MORE -> Settings. You can change the game language here, under GAME: SELECT LANGUAGE.
However, there are three unusual scenarios you may encounter (especially with older, or smaller games):
- Some games may have all language versions bundled by default. In this case you will have to select the right one in the game options.
- In some instances (most usually for some older games), you will have to use a Language selector. To open it, select the game from list on the left-side of Galaxy, click on MORE -> Other, and look for a Language Setup, which is a separate application used to change the game's language.
- Some games may only have the English version available.
