Well, I disagree that it's losing so much detail - the effect is subtle in the extreme (whu?) - but I concur that it's a shame. The thing about the way Valley looks, dissenting opinions aside, is that it really is rather beautiful when viewed as a static art piece.
Sadly in motion it's just too much for some, like me. I'm all about game first, graphics later - and actually here I find the explosion of colour and detail impedes my ability to play. For me, that's bad!
