I’ve always wanted to create a stone age mod, but I didn’t really get introduced to Civ IV until BTS and never got around to making a significant mod other than XML which anybody could do. This time I’m going to try it when the tools are released. I started with the tech tree today after reading a bunch of websites and looking at Quot Capita (http://forums.civfanatics.com/showthread.php?t=261143) and Stone Age Mod (http://forums.civfanatics.com/showthread.php?t=327654). Please let me know what you think about anything. There is already a lot of discussion about Stone Age in several other forums so I don’t take credit for anything of this. Most of I’ve read in the last few weeks has stated the Mesolithic era (the last part of the Stone Age) started somewhere around 10,000 B.C. The end of the era has varied depending on the region but all references I’ve read states the end of the Mesolithic era is agriculture. So, I based my tech tree off of that. What I had envisioned for my stone age mod is just like in the Quot Capita kind of. Never played the mod but from the thread I believe it would be similar. First, your city would follow a nomadic lifestyle moving from place to place where ever food is present. There would be two different kinds of “workers”: gatherers and hunters. The gatherers would gather food from sources such as grain, wheat, etc while the hunters gathered food from sources such as bison, cow, deer, etc. After a set amount of turns the food source would be temporarily exhausted for a number of turns which would force the nomadic village to pack up and move. The exhausted resource would come back after a set number of turns, so it’s not wiped off the map completely but not quick enough you would want to stay in the same place. With the tech river fishing it would allow you to get food from any river nearby. I would still want to promote grains and animals so I don’t want to the river to be a great source of food. This is the basics of what I had in mind and I have a few more concepts at the end. And last, I don’t want this era to be extremely long either. You’ll notice in the two links that there are 20-30 techs in this era. I think people would get bored if you followed the nomadic lifestyle with one city for a really long time but that is just my opinion. So, I don’t have as many techs as that (15). I could add a bunch more but opted not to for this reason. Below is my explanation for my tech placement. It would be a lot easier to get comments if I explain my reasoning. Gathering – I really like how ever leader in the game in Civ 5 starts with the same technology. It also makes a lot of sense after doing my research why they choose agriculture. Agriculture represents the end of the Mesolithic Era and the beginning of the Neolithic Era or what we call the ancient era. So I wanted to follow this methodology and I thought gathering would be a good starting place. Hunting – Hunting really kind of make sense on its own but I wanted to follow the agriculture methodology like in Civ 5 so I made gathering a prerequisite. Fire – I figured they had to gather up wood in order to burn it so gathering seems like a logical prerequisite. Stone Tools – They also had to gather up stone to develop the tools so gathering seemed like a logical prerequisite. River Fishing – Stone tools and hunting are prerequisites for this technology. I figured they needed stone tools in order to actually fish and you are also hunting. It may be better to Cutting tools as a prerequisite. I couldn’t decide. Basketry – I had a hard time placing this and there really isn’t any logic behind it. Open to suggestions. Clay Pottery – Pottery during this time period was done using clay and fire so I figured fire would a logical prerequisite. Pigments – One of the primary pigments of the time period was Ochre which was derived from clay. I figure they had to dig up the clay using stone tools so it seemed like a logical prerequisite. Other pigments of the era were charcoal from burning wood so I added fire as a prerequisite. Cutting Tools – Using stone tools as a prerequisite seems logical to me I can’t really add anything there. Petroglyph, Rock Art, Jewelry – Petroglyph is an early form of communication on stone. So I figured they had to cut the rock (cutting tools) and write on it using pigments. The other two technologies pretty much used the same principle. Rock art and jewelry are dead techs on purpose. I figure they could lead to some early culture buildings as a reward. Ceremonial Burial – Requires petroglyph as prerequisite. In case they want to write on the gravesite I thought they would use a petroglyph but I don’t really know. Open to suggestions. Basic Construction – requires basketry and cutting tools. I figure cutting tools are needed to cut the necessary material. I figure basketry is a version of even simpler construction so it seemed logical in my mind anyways. Sedentary Lifestyle – I wanted to pull the tech tree together before leading to agriculture so I choose ceremonial burial, basic construction, river fishing, and clay pottery. This should leave only rock art and jewelry as not necessary. OTHER IDEAS 1. Resources Ideas – Wood, Bone, Stone, Shell, Antler, Berries, Nuts, Basalt, Sandstone, obsidian, Bison, and Amber 2. Units would be limited to a certain range around the nomadic settlement. In my mind the farther ways from the settlement, the harder it would have been to get the food back to the settlement. 3. I thought city states wouldn’t show up until Ancient era but I don’t know. 4. Obviously no settlers would be allowed until sedentary lifestyle or agriculture. 5. I thought about the idea the food itself moved. (i.e. every turn each food source such as cattle, deer, bison, etc. had a random chance of moving to another hex). Do this instead of the food getting consumed or they could both be done in conjunction. 6. Getting food from rivers would be unlocked after river fishing. I was thinking it would give very little food in comparison to the other sources but would be a neat addition. I think it is important for ROM to get the Stone Age the way you guys want it because the rest of the tech tree adds to it. And I remember changing the XML that if you change something at the beginning of the tech tree it affects everything and is extremely tedious. These are just my ideas let me know what you think. Try not to be too harsh I’m not the most creative guy. I just got the information from google after reading for a few days.
