Well, you could spice things up by helping other factions out. If you're rolling in cash, you can afford to hire a full stack of mercenaries and intervene in Greece or Syria, supporting one side or the other. You could reduce the threat from the Ptolemies by helping out the Seleucids, for example, ensuring that the Ptolemies don't get Antioch and become too powerful. Your eventual goal is to recover Phoenicia (Sidon) for yourself, so you have a natural interest in that region.
