If you implemented my Civ3 edit file, your game would crash repeatedly. You can't just play any set of rules, without changing the PediaIcons.txt and Civilopedia.txt files. Even with correct text files, if you do not have the corresponding art files, or they are not in the right directory, your game will crash. This is why we say, go download a completed modpack, rather than just a bic/bix/biq file.
