I finally got around to trying this civ, love the concept!
Ill just post some notes here in case you want some data and thoughts
Starting Settings:
Large map
10 civs, 20 city states
Map: communitu_79 or whatever the "standard" vp map is called these days
Immortal
no 4UC
What I ended up with:
CV on turn 311
Tradition/Statecraft (duh)/Industry/Freedom
19 "manufactured" city states. 3 from conquest, 16 from settlers, only one of which got conquered
14 embassies
25 city state allies
28 trade route slots, but I got 3 of those within the last 10 turns
Comments in no particular order:
At this point I have a sample size of 1 game. Take this with a grain of salt.
The city state founding mechanic is the most hilariously fun thing to use. Finally, I can get back at the AI for all of those garbage cities they settled next to me by settling even more garbage cities next to them!
Much talk has been made recently about how OP Austria is with marriages and shutting everyone else out of the world congress. This felt very similar to that experience in human hands. Austria can steal other people's city states and keep them forever, but I didnt really even care about that because I can just make more. At the end of the game there were still 4 more spots where I could have put cities down, and due to my extensive trade route network, I can keep most of them. In renaissance, I already had 5-6ish embassies, enough to shove my religion through the congress and pass almost anything else I wanted. (Although it didn't hurt that I gave Germany my religion too)
It feel like this could be easily countered by a human opponent. Whats Phoenicia going to do if I start conquering his city states? Fight me? Assuming Sur itself does not border me, a 1 city civ cant make much of an army to project force. The city states themselves are such incompetent tacticians that all I would have to do is wait for them to impale themselves on my defenses and then go conquer them. In this game, Pacal declared war on me, was surrounded on 3 sides by my city state allies, and managed to fight them all off before I got involved. How much more could a human do against that?
Put together I would say this balances out. If you can make it to the endgame you have an insurmountable vote advantage, but your way there is very brittle. Like tradition in general, but pushed further.
Putting a city state between you and someone else appears to be the most effective way to get them to like you. Shaka hated my guts until I forward settled his capital, and then he was my best buddy until he got wrecked in a 3 way war.
I will probably turn off the barbarian city state invasion quest the next time I play as Phoenicia. I had barbarians on my borders and plundering my trade routes almost constantly from classical to about renaissance. It made trade routes basically unusable until the quests stopped appearing.
This has already been discussed to death in the spy thread, but spies hit tall civs like Phoenicia really hard. Losing a third of your science for 20 turns is a massive hit and there's nothing you can do about it.
Military supply felt fine. My capital was enormous all game and assuming I could make the units in the first place, supply was not going to be a problem for defensive purposes.
No bugs as far as I could tell, and everything worked as I expected it to
All in all, this has the potential to be one of my favorite civs to play as. Unique and the game goes by quick due to lack of micromanagement.
