I second the recommendation for Red Dead Redemption. Fantastic game.
Though I have to disagree on L.A. Noire. Love that game. Insanely detailed recreation of 1947 Los Angeles. The attention to detail is insane and the size of the map is very impressive. And pile on top of that classic film noir storytelling and baby, you got a stew goin'.
I can second the thoughts on attention to detail. The map is nearly 100% accurate... I recognize some things on the map from today, like old theater marquis (though the businesses below them are obviously no longer movie palaces.)
It was fun but I didn't finish it. Happens a lot to me, actually.
