Eh, I don't know if it's necessarily long-time gamers but PC gamers certainly aren't impressed with graphics often. People foam at the mouth for Killzone 2 graphics but it just looks like year old PC graphics with good lighting to me.
I'm 21 though and I've been gaming basically my entire life and I tend to care less and less about graphical prowess every generation. In the late 90s they were practically all that mattered to me. In the PS2/GC generation I found they were important, and in this generation I'm mostly uncaring to them, despite owning what's by far the most graphically impressive console this gen, the PC.
There are a lot of things I'd place above graphics. gameplay, good sound track, good artwork, good voice acting, well contructed story, physics, good (non-repetitive) design, and replayability. I of course want graphics to be clean, but past that they just need to create a suitable atmosphere for the game.
