Super Metroid is the greatest game ever made, IMHO. Awesome GFX art direction aside, the music was INCREDIBLE, nearly on par with Turrican 2. ;-)
Dunno why gamers say SNES can't scroll fast... Samus picks up some serious pace.
Donkey Kong Country, Earthworm Jim = very fun, great character animations, but there's a sense of hollowness once you were over the presentation.
Some level design in DKC was simply unfair. Remember the mine cart rollercoaster? Trial and error, no improvising.
Cybernator is awful, IMO. Those interrupting dialogue boxes that popped up... three words per line. And the controls = steep learning curve. :-(
