the rain at the beginning of a link to the past was pretty class, if you had decent sound set up back then could put a chill in your spine, especially how it kinda echo'd when you were indoors.
the start of super metroid was fairly impressive too for rain, the fact that it falls on you while you are outside the cave but as soon as you enter there it stops, not bad considering it was a 3mhz processor behind it :D
naturally metroid primes rain can't be praised enough, especially if you stand still and look up how it changes from just running down your visor to causing drop effects all over the glass, currently replying that atm and my god it's still beautiful, was using it as a test of what Gc games would look like on our new 42in screen and Metroid absolutely holds up still even today.
