halo 3 is the most impressive to me of anything released so far, but like any technical achievement, i'm hoping that we see games that beat it sooner rather than later.
those screens and gifs of uncharted don't do much to convince me... but then i doubt screens and gifs of halo 3's lighting would do it justice either.
uncharted looks to have some impressive shadows, and i love the colour rich look of the game (perfect for it if you ask me).
then again, the lighting in the game could be better than halo 3 and without a mode where i can pause and move the camera anywhere i want, i'd probably not really notice.
i so hope more games start using that feature. it really allows you to appreciate the work done on a games visuals, and a game like Uncharted would surely benefit from it as much as Halo 3 has.
