why not adding the spartans instead of minoans they are far more interesting
Because both the Mycenaeans and Greeks (who represent Macedonia) are in this game. This means that Spartans are technically already covered. I think it would be pointless to continue to add Greek civilizations to the game when the need for them is low.
Having many Greek civilizations is integral to ambrox's and Numitor's mod - it's called "Greek Epic".

Minoans, however, would be historically separate and not already covered in the mod. Also it would give another trading civ into the game - as opposed to another conquest civ. I always welcome new naval civs.
