Need for Better Tech trading

[dirtyparrot]

I think that one of the things that need to be tweaked is that you should be able to trade techs along the same tech path in one trade. Say for example, another civ had Military Science (cost: 2000) and you had Paper (cost: 600) and Education (cost: 1800), you wouldn't be able to swing a deal since you could only trade Paper and Education in successive trades.

An idea that intrigues me is that trading should improve relations in defined way which is clearly shown and can be calculated beforehand
