As an aside: Inspired by all this talk I've come up with an alternative to the a linear scale for technology. Instead of having tech levels, all societies have a set of skills, like characters, defining the level of knowledge available. For example: * Stone Age: Craft (Stonework) 1. * Bronze Age: Craft (Metalwork) 1, Craft (Stonework) 2. * Iron Age: Craft (Metalwork) 2, Craft (Stonework) 2. * Medieval: Craft (Stonework) 3, Craft (Metalwork) 3. * Renaissance: Craft (Stonework) 5, Craft (Metalwork) 4, Craft (Clockwork) 2. The different levels correspond to certain aspects of work. For example, Craft (Stonework) 1 would equate to simple working of flint, whilst Craft (Stonework) 5 would mean Renaissance-levels of elegant stone construction. Similarly, Craft (Metalwork) 1 could correspond with simple Bronze Age metal work whilst Craft (Metalwork) 5 could correspond with fine swordsmanship of, say, Shogunate Japan or the Renaissance. All skills are capped by the levels in their particular culture. So, a medieval blacksmith could only gain Craft (Metalwork) 3 at most. In this way, all metal objects from the Medieval period are of a poorer quality than, say, Renaissance. Similarly, all objects have a prerequisite levels of Craft skills required to manufacture them. For example: * Flint Axe: Requires Craft (Stonework) 1. * Short-sword: Requires Craft (Metalwork) 2. In this way, a steel short-sword will not exist in the Stone Age but a Medieval flint axe will be superior to a Stone Age one. This makes it easy to create "alternative history" technological (for example, a Medieval period with a Renaissance-level of metalworking). Just an idea.
