Ah yes, games with good writing. Difficult to come by. Not sure why. Maybe because you can't put writing on a trailer?
Of course, here I'm opening myself for a valid criticism which might be constructed as "even if a game uses elements of previously told stories and settings, it might do a different spin or do it on a such a new level of excellence (story wise) that it becomes incomparable with previous attempts".
You could also point out that trailer can be manipulated in such a way by a talented director, that would make the game appear new and unique.
