Of course looking good is nice but gameplay is still paramount for me. After PSX, many of the games developed put out only graphics as their main forte, leaving gameplay just equal if not mediocre or even worse compared to their earlier editions.
Most present day multi-disc games still leave me unsatisfied with the action/ story while earlier single disc games sufficed. I feel all that memory and hardware were utilized only to give me a good picture.
So long as gameplay is good, I wouldn't care if I got to play it on a GameBoy screen.
