I bought Metroid II the day it came out back in 1991, and since that day it has been my favorite Gameboy game, and one of my favorite games on any system. The graphics were far superior to its NES predecessor, which made me love this game from the start. The game play is extremely easy to pick up, and very responsive to what you want it to do. AND, the levels are vast and fun to explore for a few hours. Let's face it; it doesn't get much better than playing as Samus and shooting up the Metroid.
