Ok I think I need to shamelessly steal from Stars Without Number, some table like this. Instead of doing the warhammer feral world feudal world forge hive world etc the tech should be a separate d100 roll the idea is to make it about 80% useless 15% viable and 5% superadvanced.
The primitive barbarian worlds can still be used for mining or agrarian things or as pleasure / garden worlds (SLAVES ENSLAVE EVERYONE sword and planet LOINCLOTHS). Also I think an interesting mechanic might be that you cannot upgrade the tech level of the world too fast or out of sequence because of the aforementioned FUTURE SHOCK psychic meltdown hehe, so you cannot take a norse barbarian world dump space travel and just turn them into 40k Space Wolves lol maybe you have to advance through the ages for civilisational stability... unless you want to experiment with some psychotic psychically aggravated populace hehe.
I am also trying to research what elements might actually be quite rare in space. From what I have read, water is actually not that rare, also most metals are not that interesting either (apparently, phosphorous, which is needed for agriculture etc, might be quite rare on a galactic scale? Not too sure about this) I think the other way of doing this might be just some 4X videogame style magic resources eg "Dust" from endless space 2 FIDSI or some Crystals lol THE SPICE
