new version up, more or less complete up to the Sunga spawn in 180BC.
new feature: units that require resources are limited to a six per resource instance controlled by the player. so if you control 1 ivory you can build 6 elephants, if you have 1 iron you can build 6 total of armored units. there is a tooltip to show you how many more units you can build. texts describing ancient Indian armies consistently list vast numbers of light infantry and relatively few elephants and cavalry and I wanted to reflect this, as well as making controlling multiple resources more important.
the tech tree is done up to the early medieval period but is probably very badly balanced.
and the city name map is not complete but much further along.
