WI Pyrrhus of Epirus lived?

[Blue Death]

The ancient historians here will recall that a certain Pyrrhus of Epirus campaigned in both Macedonia and the Roman Republic, however in the latter he was so unsuccessful that the term 'Pyrrhic victory' was made in honour of him.

He returned to macedonia, but was killed in Argos after a woman dropped a tile on his head during a fight, and his kingdom more or less collapsed after that.

What if she missed? Would Pyrrhus carve out a small kingdom to contend with macedonia? Or would he die only a few minutes later in the fighting?

[Tizoc]

Er, Pyrrhus at the time did rule Macedonia, IIRC... But he was getting unpopular there - letting your forces rob the tombs of old Macedon kings tends to do that. I think, even if Pyrrhus would've defeated and killed Antigon, he'd still face rebellion in Macedonia sooner or later. Now, if said rebellion was to be succesful, what would happen to Macedonia?
