I was never that happy with my experience with the 3D Metriods as they felt to confining,and not deep. Although I haven't played Corruption yet. But Super Metriod is the game that got me reinvigorated about the series. Its just fantastic with plenty of puzzles,great Super Nintendo graphics and great controls. You can actually wall jump. The powerups,upgrades and special abilities you can acquire,as you go,are always rewarding to find. Altogether the game is simply a quintessential platformer style shooter with timeless and addictive gameplay. Buy it!
