Some Modding Tools Confermed!!

The game engine used in Civ V has been built from the ground up, but still boasts the straightforward python xml scripting and customization. As we mentioned earlier, the world-builder tools will ship with the game, but this time available as a stand-alone program.

As you can see, The Kartel website confirms Python, XML and a standalone Map editor, like civ 3 Link

I wouldn't use that as full confirmation. Struck me more as a comparison rather than a "Civ5 contains blah blah blah". Other sources have confirmed XML and DLL SDK as well as external map-editor. No one mentions script language yet.

Here's hoping that external world builder means they'll release it early so that the brilliant mapmakers around here can get a jump on things.

I hope they still have the in-game worldbuilder. It was wonderful for testing mods.
