One thing that i dont like about civ: our prehistoric people somehow knew that they "research" - but in reality it is not only impossible but actally less fun.
Enviroment dictate what one or other country have access for and can use for their live.
Like how africans can have woodworking if they dont have forests?
Or how you can "research" some metal if you dont have it?
Like you have iron but no copper, so you need to obtain first copper and only then you can research and use iron.
I suggest to make some of techs enviroment dependant and some meta techs what give acess but dont enable using of accessed resources.
Metals
Gems
Grains
Fruits
Skinning (need to be available only if you have access to skinnible animals)
Stone and Marble (both can be opened by same tech)
I think it is good idea for hardcore mode as it will make game more harder but in other hand more fun.
and some offtopic:
If there is knowledged or simply interested in JavaScript developer and he want to participate in creating of online game with best of civ and my enviroment dictated techs - please pm me^)
