It's frustrating finding what technologies are needed to research a specific trade good or Achievement. I've seen lots of other people complaining about this on the forums as well. Is there already a list out there that someone has compiled that tells you what to research to reach a certain objective? If not, how about we start posting them here? I've only been playing for a little while, but I'd appreciate it if others would post what they've found. I'll post whatever I find as well.
