"Realistic" graphics is very technology based. I was awestruck how "realistic" Tomb Raider was when it was originally released. It doesn't look great now.
Even classics like Metal Gear Solid on the PSOne looks awful now, whereas stylized games like Breath of Fire IV or Suikoden II still looks pretty neat.
I wouldn't be surprised that someday we'll laugh at Killzone 2's and Gears of War 2's graphics (when we have a new "standard" for realism), while still have high regard for Valkyria Chronicles' and Mario Galaxy's.
