A fairly unique list one suspects
1. Gorgo - purely because you Play in a Spartan way...and I like playing with the hoplites, not because they are OP but because they have to be together. She just works well historically but not in an OP way. very immersive for me.
2. Victoria - late benefits make starting more of a challenge but much flexibility in how to play her, and Redcoats are so strong rushed that you can play an OP game with her... miss the museum but she feels so industrial now it is great.
3. Catherine - love the spies and the new wonder power gives a nice wonder rush flavour to the CV game that was missing. One again, not OP but flexible and the early spy allowing +6 in all combat situations is not to be underestimated.
4. Khmer - super fat city/faith player allows for a lot of later game interesting options. Domray is great now, another fun troop worth getting a corps of early.
5. Kupe - flexibility and power and such a great start, you can really take advantage of this. People say RNG can be bad but at least you have choice, I have never had to restart due to a grassland start. (Only time I restart)
I've had TERRIBLE luck with Vicky. My first loss was when I played as Kongo. It was in the Original Civ game before the DLC; my very first True Start Location. I didn't know what I was doing, and so didn't rush military. Arabia quickly took me out!
I bring this up because I didn't feel bitter about it. What I felt bitter about was my loss as Victoria in Rise and Fall. There I was, enjoying a Cultural game - the challenge I'd set for myself was to build Theatre Squares late (Modern Era), when GWAM were mostly taken by other Civs, and then snatching them back by using spies. I didn't mind.
And then I realised Mapuche was running away with it, and so I declared... didn't go well, because I was in a Golden Age, you see. I had to resort to nukes (also my first experience of AI hitting back at me with nukes!). In the end, I picked back up and was busy raiding Peter when... boom! I lost. Rome had just secured a Science Victory. With all my spies busy, I'd totally forgotten to pillage his Spaceports (I remember Rise and Fall AI wasn't good at repairing them either).
I gave up on Victoria. When I next tried again with her, it was post-Gathering Storm. I was rushed by my close neighbour Khmer, who had spammed Heavy Chariots. I lost the last city by loyalty, I could do nothing, but watch my loss come.
Intent on not giving up, I tried a third time only to be rushed even earlier by an even closer neighbour! The units? War Carts. I stood no chance...
The games I've enjoyed the most have involved:
- Kongo. Just a fun build. Making neighbourhoods is actually exciting with them
- Peter. A well-rounded Civ. Religious Victory with a tundra start and Yerevan is like playing on easy mode
- Macedon. I've never had as much fun warring as with Alex
- Mali. More money than you know what to do with!
- Germany. Yeah, Hansa Addiction ought to be added as a real disorder!
