Epic War Age (EWA) - Adapted Mod Collection

When the game loads, it displays an image of one of the city types. I like the rotation itself, but is there a way to remove some of the cities? Some races are a bit disappointing.

If possible, please tell me which mod to look into – I can remove the unnecessary ones from the archive myself, or if there's a config file in the corresponding mod with a list of race names included in the rotation.
