Thank you for the replies!
AFAIK tech costs scale only with the galaxy size - the larger galaxy, the higher the costs - up to huge.
Thats good to know; I consistently tend to play large, with occasional mediums. Thanks for the tip.
So don't research it.
Of course I wouldn't research it at that price. I was using it as an example of how outrageous the costs can become.
1.5 perhaps?
Yes. Nitpicker. (just kidding)
The more research going on overall between you and the AI, the more costly it is to research. I don't know how it is calculated, however. Sorry.
Hrmm, I expected that the scaled tech cost was dependent solely on my amount of research. Are you sure that the AI empires are factored in? If so, doing massive research early not only gains you a tech edge, it forces the competition to devote more resources. Perhaps thats why the AI is so happy to trade techs...
Thanks for the tips. I might try to track down the formula when I have some time.
