I've been working on my own system, which just by coincidence correlates really well with the system in the Ravenloft campaign sourcebook. The main difference is that while Ravenloft goes from 0 to 10 and stops at the Reformation Era, mine goes from 0.5 to 5+ and allows for fractional tech levels. (The Ravenloft TLs would be like tech level 0.9 through 1.9).
The tech level of an item would be the level at which it becomes invented. The item can be made before then, but the further back, the harder it is to make the item. Perhaps -10% cummulative for every 0.1 level difference. (-30% at -0.2, -60% at -0.3) If the penalty is 100% or more, then the Legendary Inventor Legendary Ability is required.
I'm still basically GURPS-ish with regard to using an item. Primitive warriors would have no problem with a sword or a spear, and if you showed them which way to handle a lightsaber they could get the gist pretty quickly. Modern soldiers (tech level 2 or 3) would not be familiar with swords or bows, but would be familiar with guns.
For the record, currently our society is at level 3.08, identified by the widespread usage of camera cellphones. The modern campaign I am contemplating is set in the 1970s, or level 2.8. The World War II game I ran was level 2.6. I estimate level 3.0 was achieved approximately 1995. There is a kind of "Toffler effect" in that it may take thousands of years to get from 1.0 to 1.1, but only 15 years to get from 2.9 to 3.0.
