it is pretty simple, a game isn't good with bad gameplay, let the graphics be as good as possible, but better graphics for the same game improve the experience. it is a very simple formula. walk through a game with great gameplay and average graphics and you will like it a lot. make the same game with awesome graphics and you will like it even more. as better the graphics as more you will enjoy the world you are playing in.
the difference for me in a game with awesome graphcis or only average graphics is, for the game with average graphics i need 10 hours to play through, the game with awesome graphics need some more hours for me because i really enjoy the world and i will stand still plenty of times just to look at something because it looks so wonderful. if i see average fire in a game, i don't care, if i see the best fire i have ever seen in agame, i will stand there and look at it few minutes just because it looks so unbelievable great.
when i first played uncharted 2 i was wasting hours just to look at the environments. if the game wouldn't have had these graphics i wouldn't have done that. i wouldn't have thought "wow just look at this small mountain village, it is sooo wonderful"
