Metroid 2: Return of Samus expands on the original title nicely. There’s still no map for the game’s giant world, which isn’t necessarily a problem due to the game’s linearity, although it can be an issue if you put it down for a while and don’t remember where you got to. There’s a decent amount of exploration and hidden items to find, and the hunt to find and kill the 39 Metroids is fairly fun. Although nowhere near as refined as the 2D masterpiece that is Super Metroid, Metroid II has held up better than the original NES game and as such is still very much worth playing. Of course, the 3DS remake is arguably the best way to play the game these days, but the original still has its lo-fi charm.
