On the subject of leaders and historical awareness:
Why not use this opportunity to educate the civ community. Just because people may recognize one leader more than another, does not necessarily equate to the more recognizable individual being a better choice. I see no reason for not using the mods as tools for disseminating historically accurate information.
Since we are the ones making these mods, why not pick the greatest leaders for these new civs. I know we have civers from all over the world on these boards, so why not take this opportunity to educate the rest of us on who you consider was your civs greatest leader.
Just because most people might consider a leader obscure, people in the know will know that that obscure leader is a better choice than some more recognizable leader, and we as a community have our level of awareness raised that much more by including the obscure leader. By using the obscure leader and including a decent civilopedia entry, that civilizations history is done real justice and the mod creator doesnt look like an uneducated country bumpkin.
I know, that I do not know everything about all these new civs that are being proposed, and I would not dare to suggest that I know who should be the leader of most of them. I have some ideas about a few of them, but I defer to those people who are more knowledgeable. I do know, that Joan of Arc was never a Head of State, she lead the French army for a short time, but that does not qualify her to be a leader in Civ3. She could be added in the Great Leaders list, but not the Civ Leader. Likewise, Ghandi is a horrible choice, as far as I am concerned. He lead a peaceful revolution, but he is an inappropriate choice for a game such as Civ3 that involves much more warfare than Ghandi would ever approve of. Having one of the most peaceful people of the 19th and 20th Centuries.
So, for the betterment of the community, I suggest that we not necessarily go with the obvious choice, and instead dig a little deeper and provide an educational experience along with a fun gaming experience.
