I read a strategy for the Seleucids and searched for this, but it wasn't really helping. Anyway, I started up a seleucid campaign today. I've never actually won a campaign as them. The campaign starts, and I see a very weak economy with almost no infrastructure. I set to work upgrading my cities with a focus on military production in Antioch and Seleucia. To secure my Southern Border, I sign an alliance with the Egyptians. First five turns are okay, but then on the sixth, Parthia signs a trade agreement with me -then attacks my city. I get a message saying that Egypt has broken our alliance, and signed an alliance with Parthia. They also siege one of my cities. Then Pontus and Armenia follow. At least the Greeks are too busy, but by turn 15, they're also knocking on my door. And every turn until I ended the game, at least one of my cities was put under siege. Every turn. I played for 20 turns, and racked up 80 battles.
I've used hoplites. They're beastly in this game, they made the campaign my easiest, but pikemen to me are just horrible. If this is what the Seleucid army relied on, it's no wonder the empire collapsed. Sure, it may have a better reach than hoplites, but when 3 out of 5 of your neighbors have armies built around horse archers, that's not going to cut it. Also unlike hoplites, pikemen are almost useless if they're not standing still. I'm not lying when I say my unit of phalanx pikemen were routed by archers -in melee- when I ordered them to advance.
This incident of my pikemen fleeing from dreaded archers in hand-to-hand combat made me quit the campaign. I decided to load up a custom battle to see how effective these things were in melee from their strongest position: stationary, pikes forward, with a fight from the front. I made two units, one of Eastern Spearmen, and one of Pikemen. The pikemen lost. miserably. I decided to try another fight, but this time with a fully decked out silver shield legionairre against armored hoplites. This time, I thought I was going to win, but the AI was just screwing with me. It sat there, bugged, for a full two minutes as I chopped away at their flank before finally it, with 15 men left, turned to face my legionairres, raised their shields, and routed them.
