Short answer: Yes it has. People really didn't start keying into how "ahead of its time" the GW AI's exposition was until people made video essays elaborating on it many years later, which I always thought was weird because I started seeing how much it was making sense back in, say, 2005-2006. And I was barely a fucking teenager back then.
And everyone hated Raiden basically because Kojima baited everyone hard in the promotional materials that MGS2 was going to be another full on Solid Snake game with nary a mention or hint of Raiden's existence. It got further compounded from there because Raiden was like the antithesis of Snake: He looked young, almost effeminate in how "pretty" he was, he came off very much as a greenhorn on account of all his "I HAVE OVER A GORILLION HOURS IN VR TRAINING" talk juxtaposed against the existential crisis he seems to have over the fact that the real action is so much more different than his training (with most people kind of glossing over the subtle foreshadowing of his unconscious upbringing as a child soldier expressed in his complaints), he talks about his feelings, he complains about the straightforward, almost inhuman nature of his orders (again, more foreshadowing which a lot of us glossed over), and he lacks all of the sardonic charm and charisma that Snake had as a veteran soldier. It was only when people started playing through MGS2 multiple times and actually paid attention to the narrative devices used throughout the game did people start seeing the supposed "genius" in Kojima's writing and learning to appreciate it.
