I've recently been playing Uncharted 3 in 3D after completing single player in 2D, and I have to echo the comments of previous users regarding image quality. Like several other 3D games, the drop in resolution coupled with an apparent lack of any anti-aliasing result in an image that looks too jaggy for my tastes. On my TV it also suffers from considerable crosstalk, which can be distracting. It's not surprising that this game requires such a compromise in stereo 3D since in 2D it's a spectacular visual feast. It's a shame too, since the feeling of depth is fantastic and the framerate remains solid. I'll probably still give it a playthrough in 3D, but if any game has made me consider that we're far overdue for a new console generation it's this one.
I'd also like to revise my opinion of ICO in stereo 3D somewhat. Though I still prefer full 1080p, after playing a bit more my statement that depth is generally slight only really applies to indoor areas. Once you step outdoors and catch a glimpse of the game's beautiful vistas in 3D, it's hard not to be impressed. It's probably worth turning on 3D at least in those areas, but SotC is still the better stereo 3D showpiece.
