Meeting "smaller" races has been in 4x games for a long time. Even in MOO II you could find a planet with some special farmer people. Its in CIV V and in Elemental as well. I have a problem with the way this is evolving in modern games. These smaller nations are just there to be played with. I want a living world were everything can happen. When we look at world history there has been city states, but that was not because of faith/god/allah or someone decieded that they were city states. They just didnt evolve to empires.
In 4x games the gamemakers deciede who will never develop beforehand, and that is wrong in my opinion.
1. I like the concept that there are minor nations different from the normal ones that you can choose to play with
2. I want to give them freedom to be much more active. In CIV V they give you food, culture or whatever. Its totally boring. In Elemental they can give access to some special units, which is fine but rather one dimensional.
What I would like is for the Frog to make a special Minor Nation AI that would make them come alive. Since they have access to special and strong units, they would win the game every time if given the same options as normal AI nations. Give them soul.
Some could align to the Empire and some could prefere Kingdom.
Some could sell you units if you do a quest for them or if you bribe them
Some could deciede to expand if there is much free land
Some could attack and be very hostile if you settle too close
Minor nations could attack eachother if their borders are closing
Their pioneers could be made rather expensive to make them slow starters (compensating for the strong units)
A MINOR NATION SHOULD IN EXTREME CASES BE ABLE TO WIN THE GAME!!! That would be soooo cool.
