This mod has by far one of the most complex and broad ranging tech trees I've ever seen, rivalled only by the sorely underrated Call to Power series. It's sheer scope is one of the biggest things that got me into C2C in the first place, and I look forward to seeing a greater fleshing out of the second C thanks to the talents of MrAzure, even if my mind is baffled by talk of transapient sophonts or other such ontological transubstantiation. I offer these as honest queries and constructive criticism to provide an answer to things that have been gnawing in my skull about certain technologies and what they represent for a while. So without further ado; Naming Questions 1. What does Nomadic Lifestyle refer to? The first migrations of early hominids out of Africa (1,800,000 BC), the similar exodus of Homo sapiens (125,000 years ago), or an even earlier state where hominids or humans transitioned from an Edenic Golden Age lifestyle of living off fruits and berries (not even having thought of gathering them at this stage) to a harsher lifestyle that involved moving and gathering resources from location to location? 2. What about Gathering? Would it be a lifestyle based around stockpiling foods rather than always eating them on the spot? Because such behaviour can be observed in many birds, let alone primates. It would make more sense to me if it connotated a gender dimorphic hunter gatherer lifestyle, but even that has it's precedence in the rest of the animal kingdom. 3. I am currently operating under the assumption that Cooperation refers to social structures which are bonded by any factor other than close blood relations; the game starting with "the family", this tech bringing "the village" (or the nomadic group as technology permits) and Tribalism "the tribe" mentioned in the classic intro to Civ IV. 5. What does Hunting represent as a distinct technology from Persistence Hunting, Trapping and Tracking? Is it the usage of tools that is the differentiating factor? (i.e. the spears Ice Age humans used to herd their quarry, typically a mammoth, down into tar pits from cliffsides? 6. How are Ideograms distinct from Petroglyphs? 7. The exact distinctions between Masonry and Construction are decidedly unclear; the technology for crafting the Pyramids and Stonehenge is clearly different, but is it truly the physical technology rather than the culture and the scientia that delinates the Pyramids from the Pantheon? 8. Similarly to 6 and 7, is it complexity or material that distinguishes the likes of the Venus of Willendorf from Sculpture? 9. Code of Laws is very ambiguous. It uses the Ten Commandments as it's image and sources it's quote to Hammurabi, yet Hammurabi's Code requires Dualism and it comes well after these roughly contemporaneus works. 10. Surely Calendar would date back to Sumerian days? Or is that covered by Stargazing? 11. What precisely is Cloud Patterns and how does it differ from Agriculture, Calendar or Stargazing? 12. Ditto for Astrology Placing Questions Leaving the Prehistoric alone, as I know that's a touchy subject and DH and johny smith have said most of what I want to say anyway... Firstly, and perhaps most importantly, what time period is Ancient meant to cover? This is relevant to a modmod I'm working on, as well as my soundtrack pack; I'm unclear as to whether it is the Neolithic, Chalcolithic, Bronze Age or some combination thereof. Both the Chalcolithic and Bronze Age are merely two x columns wide in the tree, while the Iron Age gets at least 6, with merely 2 left over for the 0-500 AD period, and nothing for the post Alexandrian/pre Imperial Roman age. Meanwhile, the Medieval Age gives 2 columns to the Early Middle Ages (Feudalism-Heraldry) and to the High Middle Ages (Heraldry-Chivalry) and 3 to the late (Chivalry-Gunpowder). Of course, this is all rather Eurocentric, but it is thought by some scholars that the Renaissance was triggered by the arrival of a Chinese trading fleet into Venice, and one can find parallels to the way of chivalry in concepts such as bushido in Japan. The Renaissance and the Enlightenment each get 6 columns, though with one blank for the Enlightenment. The Industrial Revolution/mid-late Victorian age gets a whopping 9 columns, with WWI coming in at Industrialism to scoop up 4 and the last 2 columns getting WWII in at Mechanized Warfare (a scale that actually works out remarkablt well, given WWII will cover 10 years and WWI 30, versus the previous age's 60). Beyond this, I have no queries or major issues; Modern and beyond have been solidly planned out and the efforts of MrAzure and potentially the Armada to Ascension team should smooh out any wrinkles in the post-nuclear ages. On more minor notes; 1. Scavenging is believed by some anthropologists to have been the first way early hominids acquired their food. Is C2C going for the aforementioned eat-the-berries-as-they-fall approach? 2. Similarly, Persistence Hunting is thought to have been the first form of hunting unique to hominids, which might raise some interests among the Cambrian to Cosmos team. 3. Tool Making dates to same said early hominid period. 4. Raft Building dates to 40,000-70,000 BC, so perhaps a more direct link to Simple Wood Working would be in order, dating issues aside. 5. The earliest form of Candle Making was practiced by the Qin Dynasty of China (221-206 BC), making it a better candidate for the mid-Classical period. 6. Alphabet dates back to Writing in Sumeria (Ancient), assuming one takes an alphabet to be a non ideographic/pictographic languistic categorical system. I'm no philologist, though, so I'm open to correction on this one. 7. The same period gave us Mathematics in the form of complex metrology, dating back to at least 3000 BC. 8. The earliest recorded Monarchy was Sumerian as well, though with some decidedly mythical dates for it's earliest kings. 9. Wasn't Road Building more of an Imperial Roman (and thus mid-Classical) development, as a national system distinct from the roads provided with The Wheel? 10. This is perhaps one I should be addressing to myself with my fanciful notions of what the eras represent, but Iron Working was a development of 1300 BC in the Ancient Near East and 1200 BC in Europe and India. 11. Glass Blowing's earliest records go back to 50 BC, so as with Candle Making... 12. Shouldn't Fire Brigades also be a mid-Classical tech, considering their prevalence in ancient Rome? 13. This is perhaps more of a "meaning" question or one better suited for discussion in my building plan thread, but if City Planning is meant to represent the kind of advanced civic infrastructure possessed by the Roman Republic, shouldn't the housing buildings associated with it be moved back to Masonry, given the existence of polytiered social stratification in housing dates back at least to Ancient Egypt, if not Sumer? 14. I remember Children of the Nile showing that Ancient Egypt had an Aristocracy outside of it's royal family, but I've no ide as to the accuracy of this. 15. Wouldn't Horse Breeding (assuming it means for aristocratic and military purposes) date back to the Bronze Age, at the very least? 16. Concrete dates back to Ancient Egypt, and natural formations of it have been found dating back hundreds of millions of years. Unless there's meant to be a distinguishing mark between it and Masonry, rather than being about the material itself? 17. Insurance, to my great surprise, appears to be placed too late in the three, not 3 eras too early, as forms of it date back to 3000 BC in Babylon and China.
