What I mean by this is at some zt2 sites they had a section for tutorials. Not videos so much but detailed pics categorized by buildings,exhibits, and landscaping I believe it was. The reason for this of course was to teach each other and new players the tricks of the trade. At the end of the day it created better and easier ways for players to improve at different aspects of the game. I always found them extremely helpful and anyone familiar with the zt2 round table will know what I’m talking about.
