Ya... I'm with Kilroy on this one. They still gotta have a heap of stuff before they can build nukes. The MP is a counter-balance, to stop the leading tech player from building an army of ICBM's. Theoretically, by the time the leader has finished the MP, at least one other civ would have caught up tech wise.
And as for explodin dog, the concept of a "historically correct civ" is not only a pile of cr@p, it's also against the basic principles of the game. The entire point of civilisation is to take one group of people.... ANY GROUP OF PEOPLE.... and turn them into what YOU want them to be. Everytime you start a new game, every history textbook you've ever read should go out the window.
