Interesting breakdown! It's cool to see how the civ roster evolved over time, especially with the splits starting in Alpha 10. Helps give more historical depth to each faction.

0 A.D. had a pre-planned roster of civilizations, that was fulfilled by Alpha 9. Starting with Alpha 10, Hellenes civilization was split into Spartans, Athenians and Macedonians. Additionally, the team decided to include more civilizations. Original civilizations are: Hellenes Celts (split into Gauls and Britons in Alpha 11) Iberians Carthaginians Persians Romans

market is fixable ? and how 

This is perfectly fine to do if its not a arranged pump of two players. Bad: 2 players decide to split the cheat one sells 100 batches of food for wood - sends the wood to the other player only for him to sell it for food in 500 batches. Normal: As a player notice good prices at the market and decide to convert resources for profit. Bad: Have a bot checking price fluctuations and automate converting resources at good prices

Sure I guess one thing is to use the market another to exploit a vulnerability. I guess the important thing is this has been noticed and could be a fix of its mechanic to avoid this kind of exploits in the future

Yes but if another player do the first part of trade, you are the second player and you need use the market...
