In my game as Carthage I hold two cities in Sciliy. The Greeks still have their one. Both of us are at war with th Romans. The Romans (Brutii and Scipii) constantly land piddling units of troops who consequently do nothing, just building up until I kill them. They don't come near me and do not try to besiege the Greek town, just stand next to it. There is also a large Greek stack on the island, but this does nothing to the Roman stacks. So everyone just stands around, and generals die of old age (unless I get them first)! Also the Greeks will not ally with me despite the threat of Rome. Neither will the Egyptians, the Spanish, the Gauls or the Numidians. Very strange.
