My Macedonian history is a bit rusty, but from what I remember, part of what drove Alexander the Great's campaigns was his wanderlust. I know this might require a very different Alexander than the one we got, but how far could Alexander hage gotten into Asia if he had been an explorer or merchant like Marco Polo? IOTL, after Hydaspes, he wanted to keep going into India, and maybe into China, but his men had had enough. Could he have gotten as dar as he did, or even further, without an army (or pikemen at least)?
Any thoughts?
