I'd have to go against the crowd of people saying uncharted and say:

Gran Turismo 5 Prologue. Its got amazing detail and lifelike graphics.

Uh, that's not really opinion. SMG may look great but when compared graphically to Assassin's Creed, it fails on every level.

Okami

I was hoping I'd not have to start this discussion here, but if you're asking:

Art direction is an integral part of graphics. You cannot say "well, these graphics are absolutey stunning, but the art direction is terrible". This works in both ways, as technically atrocious games can't possibly have a good art direction. Those two are intertwined, and just cannot be separated.

You can of course say Game X is technically more advanced than Game Y, or that game Y has an art direction you prefer more, but the best looking games are both technically proficient and have a good art direction.

Therefore, I'd say Super Mario Galaxy looks WAY better than Iron Man on the PS3, even though Iron Man is technically more advanced. So yes, Super Mario Galaxy is one of the best looking games this generation, even if the game appeared on the Xbox 360.

You just ruled out every Wii game right there. Yes, games like Okami and SMG have great art direction. But if the best looking games need both, the Wii is incapable of competing. 

Right now?

Uncharted

Next week? probably Ninja Gaiden 2!

 These would be my answers as well.

That's not an opinion? I'd love to hear your definition of the word opinion then.

Best graphic awards for me go to the following ones:

Super Smash Brothers Brawl. Remember, this picture is actually in game!

Amazing, huh?

joke post ?

even trying to justify a 480p game in the current gen is instant fail.

uncharted is no 1 imo

 Your kidding right? I mean that compared to this:

You must be kidding.
