I'm not sure if this was the subject of a past thread but I'll put this one out there. In your campaigns, have you ever given thought to the progress of technology? For example, my homebrew is on the cusp of emerging from the "dark ages" and entering a sort of "renaissance" I have decided that the full transition will take about 100 years in game terms and I have started to plot out what changes wiill take place in terms of technology. Things like the invention of gunpowder, new advances in fortifications and castles, as well as better quality alloys. Of course I may have to consider the effect that this may have on magic, education, and politics, but for now I just want to map out the progress of technology. Has anyone else considered this? What was your solution?
