Yeah same for me with the primitive cultures. And I don't really do postapocalyptia mainly because I'm an optimist ;D The skae are sort of a step away from that. Their civilization (and actually their entire homeworld) was NEARLY destroyed by a pan-global nuclear/nonnuclear war. Thankfully a truce was called by the wiser members of the (remaining) society and the world was saved. The skae also became a lot more environmentally conscious, using sustainable energy sources and etc. Most of them reverted back to more traditional technology, but kept bits of advanced tech, making their everyday technology a fascinating combination of modern and traditional/rustic. So their tech is styled the same way as yours, but for slightly different reasons.
