Some of your early 70's games look better than the later ones, Crysis 2 was not the best looking game in 2011, Arma 2 was not the best looking game in 2009, the best looking game in 2014 is certainly not Unity.
Crysis 1 still looks better than it's sequels to me, no mention of GT3 in 2001, No mention of MGS2 in 2002, No mention of Uncharted in 2007, No mention of God of war 3 in 2011, No mention of Shadowfall, Ascension or Resogun in 2013. No mention of ISS/first light or Driveclub in 2014. hmmmmm...
