The backdrop of Uncharted is realistic and artistic
Exactly. There's no need to separate the two. Depicting and portraying characters, settings, and so forth realistically is a stylistic choice, just as much as it is to portray something abstractly, or otherwise. Some of the greatest visual works of art have made "realistic" depictions of people, places, and whatnot.
Ultimately though, the "reality" of the game is artificial. It is crafted and sculpted to portray a certain kind of reality, one appropriate to the characters, story, and gameplay. You could say that Uncharted is "realistic" in that its depiction of the island and the people on it could exist somewhere on earth, but the "realism" found in Uncharted is not interchangeable with the "realistic" depiction of the apocalyptic world of Gears of War, or the modern day war zones depicted in MGS4. The different looks of the characters, places, and events in each of those games are good examples of how "realism" is crafted in different ways for each game's specific subject matter.
To make a long story short, the way in which a developer chooses to make something look realistic is artistic interpretation of reality, and the reality of the game. It is art, in every sense of the word, and shouldn't be discarded from a list of "artisically pleasing" games. Again, the title is not specific enough, arriving at a top ten list of "artistically pleasing" games is impossible, because it doesn't mean anything. The author probably meant "aesthetically pleasing," but even then, they would need to specify what "pleasing" meant.
