Unable to build Smiths trading company

[Jayyy]

I got the economic tech and now I am not able to build the smiths trading company. This happens with other wonders also. Why does this happen?

[Bucksfan70]

if some other nation, other than your nation, has already built it then it won't be available. there is only one per game and only one nation has it. it is this way with all the special techs/wonders

also. not sure if this is from civ 2 or what, but it think there is a hidden prerequisite. you need to have 7 or 8 cities that are larger than either size 8 (or 12), i forget which it is.

i always get adam smiths trading so i'm not sure why you can't get it to pop up. maybe try and verify your game cache if the suggestion i gave doesn't help.

I believe its because of the first requirement. There are about 4-5 nations that are about 3-4 techs ahead of me. So i believe one of them built it already.

Research different techs than the path the computer favors. If you're the only player with a particular tech, you get much more for it when trading. To maximize the return when you develop a new tech, trade it to every other player on the same turn. If you trade it to two competitors on a turn then to the others the turn following, its value will have decreased (now 3 people know it). It seems to only reassess that value at turn end. (Also that way you avoid the risk that one of the 2 you traded it to trades it themselves to the others).

This approach helps you keep up with computer player tech research on higher difficulties when they get advantages.
