Im currently in the process of a mod and its going pretty well so far. It revolves around the basic rules with a load of extra techs added. The big difference is that one of the Ancient Techs is Magic Theory, the drawback in this as it is very powerful is that it takes ages to research. Wonders become a very important factor to anyone who has Magic Theory as they all get additional abilities if you have Magic Theory. The only problem i have is with any wonder that can give free techs (such as the theory of evolotion) as it can allow someone to get the tech for free. On a side note the Great librarey could allow someone to get the tech if two others have it. So the problem is, is there a way that a tech can be tinkered with in such a way that it could not be aquired through the Great librarey or be got for free via the Theory of Evolution as a chosen tech. At the end of the day i can just change what those wonders do but i would rather not hav to do that. Basically i want this to be a tech that you must research normally if you want it, so any suggestions ?
