Before we get to the charts:
Some statistics that some may want to look at.

To find what tech level you should be at:
Formula = (X – 475) / 10
Take the year that you are at.
  1. Minus 475 from year.
  2. Divide the number by 10.
  3. Round down.
To find tech level you want to achieve by a certain date:
Formula = X • 10 + 474
  1. Take tech level that you want.
  2. Times tech level by 10
  3. Add 475

SOME VERY IMPORTANT NOTES
  • I have made a mistake when I typed in Civilization. It shouldn’t be > but rather ≥.
  • Certain Technologies are unlocked by specific flags that your country has. See before a particular flowchart to see what the flags are and how to acquire them.
  • Black arrows mean that a invention is used to discover another one.
  • Red arrows means that if you discover that invention, it cancels out a different invention.
  • These flow charts are accurate for patch 1.2
  • If I have made any error, please let me know. I apologize for the shear size, they didn't look this big at 70% zoom :D
  • "*" means the effect of a invention. If there is no "*" it means the invention does not have an immediate effect.

The tech system is a bit more indepth then I originally thought with the streams etc. Its one part of the modding I haven't looked at.

Says the guy who's been on the forum for all of three months and already has about 3/5ths the posts I do. :p

actually this statement is pretty close to the truth. All I have in my life right now is drivers ed and sport camps.

Anyways, any critiscm?

And I think it is possible for someone to write a strategy guide off of inventions and I do believe this would help tremendously.

When I first saw your charts I was more thinking along the lines of a huge tech revision mod. Unfortunately (for you guys) I do have a life, so If I do make it, it would take some time. Mostly for research and balance. (Actually writing it won't take too long at all once I have a plan.)
 
Great work. As mentioned before, I'm going to move this into the FAQ now.
