1. Pergamon being initially aligned with the Seleucids is interesting. I had initially imagined the Seleucids might subdue the Attalids but it is true that they sought Roman aid against the Macedonians first. How do you imagine a Seleucid-Antigonid War turning out and when can you imagine it breaking out? I would probably assume such a war would occur under Philip V and Antiochus III's sons. My own money would be on the Seleucids since they could call on Greek city-states opposed to the Antigonids, meanwhile, the Anatolian states almost all have marriage relations with the Seleucids. Perhaps before coming into conflict with the Seleucids, the Antigonids focus their attention upon conquering Thrace up to the Danube.I do expect the Ptolemaic territories to be divided between the two in this scenario. After that the Seleukids and Antigonid Macedonia would most likely turn on each other. Here, some of the minor players in the region, namely Rhodos and Attalid Pergamon would try to balance between the two. Rhodos and Pergamon in OTL turned to Rome for help against Macedonia, which helped to bring Rome to conflict with Macedonia. These two small powers in this scenario would likely do something similar, that is to balance Macedonia with the Seleukids to ensure that one does not get too powerful at the expense of the other.
In this case, I assume that the Seleukids would be the preferred power initially, because Pergamon was already a Seleukid vassal. And also because both Rhodos and Pergamon contended against Macedonia over control of the Aegean.
This is very interesting. I'd love to see a TL on this.
Let's assume that the Antigonids and the Seleukids maintain their alliance (with some marriages to sweeten the deal) and allow each other to focus on their own separate areas. The Antigonids focus on Greece and the Aegean, while the Seleukids concentrate on Egypt and the East. Naturally, the two states would strengthen their position and the peace would allow for population growth which could expand their armies if needed. This state of affairs could last for some time as Philippos and Antiokhos were relatively young. The Seleukids, because they avoid the OTL european involvement following the Second Macedonian War, could work instead to prevent the Parthian invasion. Eventually, once Philippos and Antiokhos have died and are succeeded by their heirs, the old peace between the two could fall apart and lead to wars between them. Most likely this starts in Asia Minor. Pergamon may well be a catalyst for such a war. These would probably last some time, considering the two realms would have had decades to build up their position.
In OTL, Titus Livius states that the Macedonians raised around 43 thousand men for their army by the start of the Third Macedonian War in 171 BC. "...except for the army which Alexander the Great took over to Asia, never had the forces of any Macedonian king been so great." Livius might be exaggerating at that last statement, but given that this Macedonia had been defeated by the Romans and reduced in territory, the fact is that this Macedonia was able to recover from the past losses in a period of peace.
Returning to your scenario, as the two realms fight a series of wars with each other, the Saka could use the opportunity to establish themselves in Iran.
2. I am very busy atm with university work (currently writing an essay about the Long Walls of Athens) but in a few weeks I should have a bit of free time to perhaps give this TL an actual shot! Albeit, I will have exams a month or so after that free week.
3. Should have continued reading before posting point 1! This does sound reasonable in my opinion. I will think of possible outcomes of a Pergamene War later in this post.
4. Thank you for Titus' numbers.
So possible outcomes for the Pergamene War
1. Pro-Seleucids Pergamon (Seleucid victory): Macedon is conquered by the Seleucids who set up a regent over the territory while the king is now also King of Macedon. Said king is declared 'Neos Alexander' and the empire is proclaimed united at last totally.
2. Pro-Seleucids Pergamon (Antigonid victory): The Antigonids conquer a chunk of Asia Minor and maybe even set up a puppet king in Egypt. Seleucids greatly weakened and suffering revolts in the eastern satrapies. Pergamon is conquered by Macedon.
3. Pro-Antigonid Pergamon (Seleucid victory): Same as above and they conquer Pergamon.
4. Pro-Antigonid Pergamon (Antigonid victory): Pergamon conquers a vast swathe of land in Asia Minor. Turned into a client of the Antigonids who also seize portions of land in Asia Minor. Antigonids set up a client in Egypt or annex it outright?
5. Stalemate: Status quo continues but the Seleucids increasingly lose hold over Asia Minor and the vaccuum begins to be filled by Pontus.
