One of my favorite worlds was world 3-1 and 2 from super Mario all stars super Mario bros on the SNES. It was nighttime with snow on the ground there were glittering stars that twinkled every now and then. World 6 in super mario bros was also a outside world that was nighttime with twinkling stars. My question is why didn't they put these kind of levels in the new super Mario bros game for the DS?
