I love graphics, but we are at the point now where I worry more attention is going into the graphics than into tangible gameplay improvements. Gran Turisom has had crappy AI (and honestly most games do) for many many years as you say. I love the new graphics but if I have to choose between GT6 graphics with good AI or GT7 graphics with crappy AI I'll pick the former. Man, looking back I really miss that simulation heavy era of Far Cry 2/Crysis/Fear. The AI in Fear, Killzone 2, and Halo 3 still represent more or less the peaks that I've seen thinking off the top of my head. Shame we haven't gone further than that after all this time. Racing games seem to often have some pretty terrible AI once you figure out how it works. Unrelated, but since I'm thinking back oh what I'd give for a native PC version of Killzone 2 with modern TAA and proper ambient occlusion.
