I bought Metroid II at a garage sale a long time ago. Child Me was never able to get into it. The small screen of the GameBoy and the lack of a map made it a challenge I wasn't willing to overcome. Now, with a map (thanks internet) and a larger screen (thanks emulation), I played through the whole game. And I'm glad I did it, at least for the satisfaction of conquering a childhood foe. It's a decent Metroid game, especially for how old it is and the hardware it was running on, but it lacks much of what made later entries to the series such good games. Even more, the game is about committing Metroid genocide, but the titular enemies are disappointing. The early ones present almost no challenge, and any challenges presented by the later ones is because they've been programed with cheezy unfair advantages over the player. It's not a bad game, but it isn't a standout in the Metroid series either.
