Im curious to know what your experience has been with client states. I know in earlier TW games they were notoriously unreliable and prone to betrayal. Early into my Macedon campaign, Athens is my client and has actually grown to be more powerful than me. They own 4 cities in Greece and I sstill have my original two. I'm quite merciful and will just subjugate my enemies rather than destroying them, especially since its so costly to occupy cities in this game. You have to spend a small fortune converting each building and dealing with an angry populace on top of that. Its just not worth it in the early game when money is tight. I've also made Tylis, the city to the East of me my client. I wonder if I should expect them all to backstab me soon or whether CA finally fixed this feature of the game and made client states reliable.
