The people who made Bioshock (which, it should be noted, a lot of them also made System Shock 2) claim BioShock is like System Shock 2[1]. I don't think it's crazy to use it to either refute or reinforce the author's argument -- it's clear the games share some of the same DNA, but there are clearly changes as time and technology marches on. I do think it's kinda weird just to ignore them, though.
