First of I have to say that the game is extremely fun to play! It is now one of my all time favourite strategy games! I started playing 3 days ago and have already become addicted! So over the past 3 days I have thought of some nice suggestions for the future updates of the game. I would really appreciate it if you could read them. Thank you.
It would be very nice to have other villages that are controlled by the computer, that also start with the same amount of colonists as you do, they should be able to advance in technology just as you can but at different speeds, depending on the resources, traits etc… that they have. You should be able to set how many AI you want in your game if any to make it custom and also add a button that randomizes that setting… With the AI added also have some of the tribes throughout the map, but have the tribes be only able to advance in better weapons, armor etc… and not any structures. So now there would be AI controlled villages around the map with small tribes inbetween them. One thing to add to this is you could add a CLASSIC gamemode where it is only YOU vs TRIBES as it is currently, and a COLONIES/COLONY gamemode where it is YOU vs COLONIES vs TRIBES.
I also thought that it would be very interesting to add different islands and ships into the game so that the player could colonize new islands around the map. There should be AI controlled villages on different islands too but not all so that the player can find an island just for themselves. There would be different types of ships for example a Fishing Ship that is used for fishing (Obviously), a Transport Ship which you can use to transport resources and colonists with to other islands and a War Ship that can be used to attack other ships/colonies and defend your island from enemies trying to take over. The AI should also be able to have ships and colonize on other islands, but obviously make it so that they colonize once they are more advanced so they dont just go around colonizing all the islands.
With the ships added into the game, there could be a trading system, it would use transport ships. But you would need to build a trading dock first. The trading dock would be used to set the ship routes and the things you buy/sell. Then the ships would sail around to different colonized islands with trading docks unless they are still not as advanced in technology to be able to build the trading dock. But if they are advanced enough they should be able to set their own ship routes and what they buy/sell from/to others. Also make it so that it all depends on the relations with the colonies so the ones that dont have good relations with each other wont buy/sell from/to each other. Obviously that would take away the meaning of the trader that comes every couple of days and make him useless. So I came up with an idea! The trader would still come every couple of days but he would sell very high-quality/rare items such as armor, tools, weapons etc… To add to this the trader would buy items for much higher and sell resources such as wood, stone, food etc… Much cheaper than the other colonies. The trader could also have treasure maps for sale that would be extremely expensive and only he could sell them to you. The treasure that you would find would be main resources such as wood, stone, food, coins and maybe 1 or 2 tools etc… The treasure maps would be rare and you would not be able to buy them everytime the trader arrives as he wont have them everytime. To not make the treasure maps OP the cost of them should be VERY expensive as I stated before… Unless there would not be much resuources gained from the treasure maps.
My last idea is to maybe add live stock such as sheep, cows, pigs etc… So that the player could butcher them for meat or collect milk/eggs/wool/leather from them. The meat, milk and eggs would be obviously used for food and the leather/wool could be used to craft the MASTER clothing so that COTTON would still be useful for crafting APPRENTICE clothing.
If you have read through all my ideas ‘down’ to this point then I would like to THANK YOU for doing so! I appreciate you taking the time! These are most of my ideas. I have a couple more, though they have not been thought through enough so I wont include them. I understand that these suggestions might not be used in-game (Probably wont) but I still wanted to give you some of my ideas for it, maybe you will be able to think of better things using these suggestions. 
(SORRY FOR ANY TYPING ERRORS)
and your typing is better than mine 
Yeah that is true his list is probably super long from all the suggestions that everyone has. I agree, the villages would add a lot of complexity to the game though, that is a very good point 
I sure will post more suggestions in the future. As said in the post Thank YOU so much for taking your time to read through my suggestions! It is very appreciated! 
I didnt even know that there was a roadmap 
I just read it and it has like 90% of what I suggested 
That is AWESOME though! Will do! Thank you again! You too
