It should be remembered that the Star Wars Galaxy tends to get torn apart by massive, nearly-the-end-of-civilization wars every millenium or so. The New Sith Wars of 2000-1000 BBY (Before the Battle of Yavin--i.e., Episode IV) did so much damage that the Republic itself nearly fell (or did fall by some reckonings), and the Old Sith Wars of c. 4000 BBY were probably nearly as destructive. And you've got pre-Republic civilizations such as the Rakata, the builders of the Corellian system, and others who are even older than that. Plenty of room for lost technology.
Thing is, even with the rise of the Sith starting around 5,000 BBY, the wars are violent and destructive, but things just aren't lost. In fact, those are the times where we see the advances in technology. Especially after the Great Sith War in 4,000 BBY, you get a massive jump in technology when the KotOR games pop up after, with stronger starships, weapons, and a galaxy that's been better explored.
Once the Republic gets estabolished, technology pretty much hits a point that maintains a status quo. There are always blasters, lightsabers, hyperdrives, starships, etc. Its just the degree of effectiveness of these things that increase over time.
Now the pre-Republic stuff definitely leaves some room open for ancient ruins, but sticking by canon, you pretty much only have Centerpoint Station left of those kind of pre-Republic things by the time of the Old Republic. Course, it would be easy to put something into the vast space that is the Unknown Regions or even the Deep Core.
To be truthful, I feel like the two KoTOR games killed a lot of the look of advancing technology. Before them, we had the original movies, a couple of the prequels showing a similar level of technology that was a bit less military focused, and then the old Tales of the Jedi comics set in the 4,000 BBY era. Everything in the comics looked different and older. Ships weren't steamlined, buildings were completely different, and just everything had a much more less-advanced feel.
But the KotOR games were set 50 years after that...and the technology there looked almost exactly like prequel era stuff. So we basically have a 50 year period after the Great Sith War and the KotOR games where there is that huge period of rapid technological development. Though it seems to be the only such time period like that in the history of the Republic.
Oh, and Ankh-Mopork Guard, a word of advice I learned from Episode 7 of
Clone Wars--in Star Wars,
never piss off the old man.
Took you watching Clone Wars for that? I knew not to mess with the old guys by Empire Strikes Back. Yoda may have just been all talk then, but you just knew he could put that cane to good use if he didn't like what you said.
