C2C Modder
Yeah I took chunks of it and put them into a translator. From what I could understand it was a good review of the game. Something to the extent of "a challenging and complex game but very rewarding".
While not a YouTube I did find this blog post about C2C.

By AvohajCaveman2Cosmos did it, including the spies thing, and maybe even the bio weapons there are ridiculous amounts of WMD's but I never play with advanced nukes option.
Seriously this mod is like the Simpsons of the Civ4 modding scene
Caveman2Cosmos (v.30)
Caveman2Cosmos a huge mod for Civilization IV: Beyond the Sword that size easily trumps all other projects developed for this series. The modification allows civilization to manage a much longer period of time. We start from the prehistoric era and the discovery of fire to eventually leave the Earth's surface and begin conquest of entire galaxies. Individual nations carry through all the way is almost one hundred hours.
To enable such a long fun authors significantly expanded virtually every block to the game content. Introduced hundreds of new technologies, heroes, wonders, units, resources, animals and nearly two thousand additional buildings. There were also fresh territories, random events and religion. This all can play alone or in multiplayer mode for up to 50 people.
