I have long maintained that for a video game to achieve true beauty, it should avoid attempting photo-realistic graphics and instead devise its own particular stylised look (see: Ōkami, The Wind Waker etcetera).
Tomb Raider Underworld may be forcing me to rethink this view. I keep getting distracted on the Thailand level and going, "ooooh, lookit the pretty undergrowth."
So, in conclusion: curse you, Lara Croft.
(On a side note, I'm rather impressed with the new graphical touch wherein Lara gets grimier as you scramble about the place but going for a dip cleans her off, but there's no way to mention it without sounding like a massive pervert.)
