@Space One & Weasel: Heh, There's already a tribal guardian, a non-buildable, non-aggressive unit that appears at the the AI's first settlement. As for graphics, every available suitable graphic from the forums has been used. Soon enough after playing you'll see; its not 400 megs of nothing. Besides, there are five warrior flavors (different graphics) for different culture groups, so creating several new graphics would have to be created for what Space One asks.
Regardless, I don't consider it problem or 'unit discrepancy'. Having two identical warriors in the build query at the begining of the game is rather trivial, and when playing higher difficulty levels, it provides extra defense (on top of the tribal guard) for the computer players. You see, with the way the normal warrior is flagged it will explore and attack, with is not good, for a variety of reasons.
BTW: Updated the biq's, as a couple rotate flags were unassigned and European ship-of-the-line was availabe with wrong tech.
