My nation is finally big enough to start purchasing tech, and I have a few questions about it. Is tech an aspect where the effects are dependant on nation size, as in an equation? For example, tech is supposed to increase the environment, are there simply flat amounts, I.E. 20 Tech = One half star? (A very rough and inaccurate example) or are the positive effects dependant on say, your Nation Strength? I'm wondering about literacy rate aswell, because I was looking for trading partners and saw someone's tech level was 22, and upon further inspection I noticed they had 1 school yet a literacy rate of 20%, which I assume is the base percent. So are there other effects other than tech affecting this nation's literacy rate, such as there military/citizen ratio, infrastructure, etc.? The only thing I'm sure on is the amount of happiness you get, which I know is a flat rate. Sorry if this post is rambling and convoluted or if this stuff was covered in the FAQ (I looked a long time and didn't find any of this). Thanks for reading.
(Also, I like the little feature of getting better tech items in the purchase tech area, like the telegraph evolving into a radio)
