Perhaps I should re-phrase - with the exception of the ultra-popular leaders (Shaka, lets face it without him do the Zulu really get in ?)
I mean
Tokugawa -> Oda
Saladin -> Harun
Hannibal -> Dido
Justinian -> Theodora
Mao/Qin -> Wu
Joao -> Maria
Julius -> Augustus
You can't deny they've taken some slightly different options with some of the other leader choices.
In addition to that:
Zara - Haile
Hammurabi - Nebuchadnezzar
Huayna - Pachacuti
Suryavarman (Khmer) - Ramkhanghaeng (Siam)
Mansa Musa (Mali) - Askia (Songhai)
Wang Kon - Sejong
Khmer was persumably replaced by Siam
Mali was persumably replaced by Songhai
