Tech's and Trading
Total newbie here so please indulge my newness. If at anytime there is someplace else I need to find info please let me know and I willl make sure to hunt there also. I have found the On-line Wiki to be a great resource so far, along with a couple of the guides I have found here.
That said, my main question is about Tech and trading. First of all I have noticed that some of the other Civ's have a tech with a * in front of it. I'm assuming this is a tech limited to that race, is it possible, for me to obtain it from them, and if I did can I even use it?
In my current game I have a pretty good tech lead and I have been able to sell off a pretty good amount of those techs between the other AI's and the minor's, is this normal, or should I be denying those techs to them? I have found that they are much more likely to spend cash on techs than making a tech for tech swap without me having to throw in 2 or 3 to 1. I don't think most games I will be able to reproduce the huge tech advantage that I have, so I'm just wondering if this is a singular thing, or if the AI is always willing to spend cash to get techs.
Thanks.
