I'm not really a "graphics" person, but there have been a few that just blew me away.

Final Fantasy VII on the PS1 was like a bombshell compared to the pea-shooter that was my SNES. It was a real jaw-dropping, holy cats moment.

Speaking of jaw-dropping, I still remember sitting there in total awe when I first popped Gran Turismo 4 into my PS2. I'm being serious, too, I can remember it clearly. It was simply majestic. For the first time with a videogame, it felt closer to being real than to being pixels.  That GT40 still gives me the damn chills.  Bloody epic.

Gotta watch that one every time I pop the game in. Oh yes. And the music is also awesome.
