Should be compatible with any other mod: does not modify any of the original files and supports mods that declare new resources, features, policies, techs, etc.

Can be used with or without Gods and Kings and/or Brave new world.

Here is the guide: writing a translation.

I welcome all translations, it's easy and fast to do.

The displayed screenshots come from an old version of IGE on a French client, before the French localization was introduced.

Besides of that, IGE comes with complete localizations in English, French, Chinese, German, Spanish, Italian, Russian and Japanese.

Most of the UI relies on the localized strings provided by Civ5 (for units' names, etc) and therefore most of the UI will be in your client's language even if IGE does not specifically support it.

It just keeps its bits shut and let you enjoy full performances. However, when IGE is closed, it absolutely does not interfere with your game, it does not consume a single CPU cycle and it has a negligible memory consumption.

Gentle with your game: IGE itself is not lightweight.

Not tied to savegames: You can save and reload your game without IGE if you want, or use IGE with a game that has been started without it.

But you're free to ignore those restrictions if you want. or not: Elements that should not be possible in the standard game (fishes on a hill for example) are grayed to help you design a natural map.

Tool tips: The detailed tool tips are here to help you better learn the game by remembering how far an element can be improved.

Social policies: Lock or unlock branches (even the ones you're not supposed to have at the same time) and grant/remove any social policy.

Technologies: Grant or remove technologies, grant a tech and all of its prerequisites at once, grant a whole era at once.

Civilizations: Change a leader's gold, faith, culture,give free techs or policies, edit relationships to seed wars or achieve a global peace, etc.

Cities: Customize the cities as you want: increase population, change buildings, change religions, etc.

Units: Add new units or remove them, give your new units up to nine promotions.

Build the world: Change terrain, feature, natural wonder, resource, improvements, routes, rivers, ownership, continent arts.

The screenshot above illustrates the tile selection (in red).

Edit a hex or paint the map: You can either paint the map (left click for 1 tile at once, right click for 7 tiles at once) or select a hex and edit it.

It was inspired by the built-in Civ4 in-game world builder. This mod provides an in-game editor for Civ5 to change the map on the fly or to serve as a cheating tool.
