I guess this is where our paths diverge. :p A game can still draw me in without being realistic; World of Warcraft is full of all sorts of little details that make Azeroth seem a lot more 'real' than most games that shoot for heightened realism (like EQ2, for example). Realism doesn't help me get engrossed in a game, but rather a strong visual style that helps you believe you're part of that world. In realistic games I seem to find every graphical glitch, blurred texture, or off-the-mark physics reaction in the game, which totally breaks any semblance of immersion I might've had.
I can see realism as being important for games like Splinter Cell or Ghost Recon, or maybe more sim styled games like Forza or Gran Turismo, but on the same token I don't play any of those, either. I guess I have enough realism in real life; when I play a game I want to go to places and see things I can't see anywhere else.
I guess as an artist myself, I feel unique art direction is more important than photorealism; I would rather play an FPS whith stylized presentation such as Timesplitters, XIII, or Halo rather than something in the vein of Ghost Recon or Battlefield 1942. I had a MAJOR problem with Ghost Recon 2, in fact...I'm ex-military, and when I'm standing right next to you and unloading into you with an M60 you should be cut in half, not have all the bullets magically bounce around you while you have enough time to drop a pistol round into my braincase unharmed. It's these sort of gaffes that really screw up the whole semblance of 'realism' in games today.
