There is also a mod called Epic Heroes. I run Epic Heroes and Worthy Heroes together. I havent checked to see if one might be overwriting the other so I might not be getting all the heros I would if I edited it. But at least Im pretty sure it doesnt crash. I also like to add Mytheology (more pretenders) and Magic Sites Mod (more sites) which kindof blows the balance thing. But great for solo play.
Toss in a bunch of nation mods and its a whole new game.
