This scenario depends on whether Darius can pull off an envelop-and-crush with the numerically superior Persians befor Alexander punches his heavies straight through, shattering the required number of units on the way.
This one is well balanced; Darius being 2 command cards down compensates nicely for his numbers advantage. The Macedonians better pray he doesn't get a couple of early Line Commands, though; that could seriously constrain Alexander's room to maneuver.
