In games like this, I have always been very fond of choosing races/attributes that grant me superior research capabilities;
However, I've noticed that being the best researcher matters a lot less than one might initially suspect, because the AI trades techs as if they were cheap Pokemon cards.
In other words, by the time I've researched a certain level of techs, I find that every other civilization has half a dozen or so techs that I don't have.
At that point, I either have to trade what I have for what I don't, or slowly fall behind the curve, as the other race's combined research capabilities outstrip my own, despite the stat enhancements.
This has lead me to start investing lots of points in diplomacy and perhaps a few in speed, so I can zip around making contact with races and serve as an information broker, trading techs for cash, influence (which I only accept as a last resort), and, of course, other techs.
While certainly advantageous, this style.... really doesn't suit me.
Is it at all viable to go for a technologically superior, isolationist state? I'm not talking about never trading, but rather of staying ahead of the pack without constantly giving away all my secrets.
