Download will automatically proceed (it it does not, Steam messed up, look at the links section - Fix Steam install) Feel free to submit new translations, it's easy and fast to do. Full localizations available in English, French, Chinese, German, Spanish, Italian, Russian and Japanese. Units, techs, and such are always localized (IGE uses the names provided by Civ5). IGE is not attached to savegames (a good thing). The first version of this mod was released on september 2011 and it is now very mature, although latest patches from Firaxis made a few things worse. Some bugs are caused by civ5 and cannot be fixed (notably, some graphics are not updated until you reload), see the official thread (links at the bottom) for more infos. If you encounter a mod conflict, please report it on the official thread (links at the bottom), I wil fix it very quickly. Should be fully compatible with every mod. Can be used on Windows and OSX (look at the Mac FAQ in the links section). Can be used with or without the 'Gods and Kings' and/or 'Brave new world' expansion. Not available on multiplayer games (of course!). Can be used as a cheat engine, a map/scenario editor, or a tool for developers.
