According to Brad's podcast from a while back, Elemental is going to have two tech trees: one for magic, and one for "conventional" technology like forges, siege engines, mining, etc. The question is, what technology should be on the conventional tree: at what period in technological development should the tree start, and at what peroid should it stop? I for one do NOT want to have my empire building power grids and racing with the Fallen to split the atom, but then again, I don't want to have one of the end-game techs be "The Wheel" either.
A good tech tree scope for me would be starting somewhat before the Dark Ages, developing animal husbandry, agriculture, and stonework (this ignores the Romans' advances, of course), then later getting to metallurgy, catepults, medicine, and basic machines like the crossbow. The tech tree should then stop at some point shortly before the Industrial Revolution, probably right when more potent agriculture was developed. May want to skip the heliocentric view of the solar system, hoewever.
Thoughts?
