So honestly, I guess I'm coming back to say that I'm mostly cool with these pages vanishing, but just as WB keeps the Space Jam website around for franchise and historical reasons, I think Konami ought to keep the websites for the big stuff around -- stuff like Lament of Innocence, Symphony, and Lords of Shadow that shifted the course of the series forever should be immortalized, and sure, aggregate the rest, but some stuff is distinguished enough that it ought to be left standing.
And the website for Lords 2 should be preserved as a warning to future generations.
