Question: Adding civs using world builder

[Stucky]

All I want to do is have an 18 civ game on the earth map supplied with Civ4.

I tried loading it in the world builder but I cant see an 'add civ' button.

I tried creating a custom game with 18 civs and loading the earth map once in game but it reloads with just the civs already assigned to it.

How can I do this?

Don't know the best solution, but what I did was I started a large game, with max 18 civs.

I then saved the game, and exited Civ IV. I then found the save game file, opened with notebad and copied the player data for all 18 civs and pasted it into my scenario file.
---I also did some quick editing of unit placement to get starting units on land and not in the water (then save file).

I then opened my scneario file and had 18 civs that I could work with.
