Well, i thought i did with the post above, but ok it will answer all question seperate. What should i say, that i agree, no i do not. Its a huge tech tree and not all is historic correct. Yes many techs are opener for resources, wonders and so on, thats there propose. Its not about real life, its a game, there are more important parts. Like f.e balance and pathing. For this you need a lot of coding experience, its not easy and can create several other problems. When we start to include prerequest Technologies for some Policies, you will see why they are there. Also some Buildings/wonders will be related to the Techs/Policies. CiV force you to start with a city, there is nothing what we can do now, without massiv C++ and Dll changes. For the balance, this will come when other parts are finished, it doesnt have priority in the first place. Laborer can only build two improvements. Yeah improvements are nice, but to create new or include some from other members of civfanatics, is a long process. Even when we do, not all will look nice in game because some parts cant be changed. F.e when some one pillage it or the differend looks when creating it. Even when you change the moai settings from coastal to every place. They will not appair on the map, its hardcoded. I already answered this question. Spoiler : For sure i know that some parts looks redundant. But keep in mind, i dont have the time for a full time CCTP modding job. So i need to do much work in parts. Iam not going to change the tech tree now, i spend so many time with the current version, that i have no interested yet in changing it. Its not perfect, but it will work for what we have in mind with it. When other parts are completed, maybe we can start adjusting them. But with Gyogen and me as the only activ coders here, we have other work to do, sorry.
