I still think it's amazing how much detail went into PSIV. Every little cutscene, everything, is just oozing with colors, shades, and it's all done perfectly! Graphically, I don't think there's any flaws in PSIV at all. (or anything that looks bad for that matter)
When I was younger, I'd look at the cutscenes and simply like the pictures, but I guess you could say that I really appreciate it now, so I pay more attention to all the little things.
