This is a terrible mistake as I'm met on the shore by a force that far outstrips my gaggle of slingers, axe warriors, and spearmen. Instead I recruit an army, smash the rebels and set sail for Crete, mostly because it's right there and I quite fancy owning Crete. 4000! Admittedly I have 6k plus in my city's storehouses, but I'm not willing to part with so much grain for measly peace. Here's Althaemenes of Pteron-a middling force in Ancient Greece-hoping for a peace treaty, as long as I give him 4000 food. Maybe that's why I receive a message from about one neighbouring leader per turn asking for my stuff. Sparta is pretty well off at the start of Troy's campaign, and the nation has good access to ports that can generate trade. Bronze and gold are much rarer, but you need them to access the best units in the game.
Food and wood are easy to acquire, and you need them to build basic buildings and keep your people fed. In Troy there are now five different resources to hoard.
In traditional Total War style, my first task in charge of Sparta is to quell the rebellion, unite the province, and start making some proper money.
