That's been quoted a lot. I thought about it, looked it up...and guess what? It's -blam!-ing bullshit. The prequels BEGIN 32 years before the Original Trilogy begins(immediate source upon google, wikipedia). So thats Ep 1- not clone wars era- to Ep 4, where we see X-Wings and such. So in a time span of under 30 years, we see the technology of the Clone Wars turn into the tech of the Civil War. And there's OBIVOUS transitions/similarities. AT-TEs and AT-ATs? AT-RTs and AT-STs? ARC-170s and X Wings? And...well...y-wings are y-wings. Improvements are fine. Make them noticeable, not just paint everything -blam!-ing black. Like, the best example of it would be TIE-Fighters have rear gunner positions, too bad that only ever comes into play once! They had the landing craft for that one scene, I guess. I also point out real life parallels- how much has phone tech increased in the last 30 years? Computer? Video Gaming? (This isnt all directed at you, but more that..excuse. Also, yes, Lucas is insane, but he did make 6 good or great "Star Wars"-es, no? Plus, via lucasarts, an astounding number of good games? Not sure if he was involved with that tho)
