So, here goes;
I figured the "low-tech" universes would contain non-existent or very minimal tech like energy weapons, shields, etc, and FTL capabilities are generally pretty shoddy. I'd include:
-neo-Battlestar Galactica
-Firefly
-Aliens (human civ. anyways)
Medium-tech would have plentiful energy weapons, shields, decent FTL, etc. Examples:
-Star Wars
-Peacekeepers from Farscape
-The Goa-Uld from Stargate
High-tech has the above stuff plus "magic tech" like phasers, teleportation, ST-esque matter replication and minute forcefield control. Like:
-Star Trek Federation
-The Asgard/Ancients from Stargate
-Necrons from 40k
Some factions don't fit totally, like the Imperium of Man from 40k; they have teleportation but rely on manually loaded shells and inferior AI. Or the Earth Alliance from B5, which fit somewhere between low and medium tech levels.
Input would be appreciated, both in where other factions might fit and also about the validity of this sort of comparison.
