Why cant people understand that there are those that want both good graphics AND good gameplay... I have never heard anyone ever say that they would prefer a game to have super graphics and no gameplay, but yet almost anyone who runs the Gameplay > graphics" rant nover stops to consider that, hey, what about both...
I've scratched it up to three possibilities. Either they don't own a PC capable of supporting high-end graphics, and just because they can't experience cutting-edge visuals - they're adamant that no-one should experience them. Or, they're flat out lying to appear elitist. Seriously, the amount of times I've seen people saying
"I'd be happier if the game had Morrowind or Daggerfall quality graphics, just so long as the gameplay was great!" But if Bethesda actually went ahead and released Skyrim with Daggerfall quality graphics, I bet they'd be complaining with the rest of us.
The third possibility is that they really haven't given it much thought. They've worked out which aspects of the game they enjoy the most (gameplay) and damn anyone else who thinks otherwise. I'm an explorer when it comes to games, so the most satisfying moments come from breathtaking views and secluded waterfalls. People who say they don't care about graphics clearly get the most enjoyment from gameplay and story, but haven't taken the time to wake up and realize just how much great visuals lend themselves to all aspects of a game. It's a shame. Just ignore them when they try and exert their own opinions as fact.
You can see trees and objects casting shadows relative to where the brightest light source is in the screenshots. It wasn't this way for everything in Oblivion, some objects cast shadows, but their contrast/brightness was not relative to the lightsource. I can see trees casting a soft shadow and a set of candles casting a darker shadow.
OP please elaborate.
In http://www.gamereactor.eu/media/59/elderscrolls5_235970.jpg you can, yes. The stools cast obvious shadows, and it looks fantastic.
In http://i216.photobucket.com/albums/cc212/darkstorne/bigimage.jpg, the light obviously comes from a setting sun off to the left of the shot. Yet the ruins don't cast shadows. I've circled an area where a shadow should be cast from a small pillar of the ruin, and you can still actually see the sun's light on the snow BEHIND the small pillar.
Trees still have canopy shadows, but even Oblivion had those. I haven't seen a definitive Skyrim screenshot to show that canopy shadows in Skyrim work differently to the ones in Oblivion yet. Hopefully one of the first videos Bethesda release is an engine showcase video, and makes special mention of lighting and shadows. That'll solve these questions once and for all.
