Suggestion for tech tree

I don't know, if this has been suggested before, but how about adding an info (a number) about how a certain tech (and its buildings concerned) will influence the overall culture of a town?

Lets take for example the choice between herbalism and secrecy. How about if you added the info that herbalism will affect culture in a certain way or not and secrecy will do that in another way or not - don't want to spoil here, that's why I don't tell which does which ;) . Maybe you could even add a number like: losing culture - 1, 2, 3, gaining culture + 1, 2, 3  (or a 0 if it doesn't affect culture at all) when using a certain tech and creating the building(s) that come with it.

That way players could make a decision based on facts and not on guessing.

I would rather like to see the prerequisite buildings in the tech tree.

I agree with Tsunami's point about the requirements. Please consider this change.

  Could we please see details, further ahead?  Even when switching ages?

But i hear some people really dislike spoilers… Too bad (and really surprising, too) there’s still no wiki knowledge base for this game, crucial for those who strongly prefers searching over asking (the same old questions) around.
