Metroid 2 is a notable step up from its prequel, and is generally a much more functional game. However, it still suffers from some faults that return from the original, such as a general lack of even the smallest amount of player guidance, similar looking locations (understandable as it was on the game boy), and repetitiveness. However, as it is a much shorter game, around 4 hours, it can be forgiven for most of these problems as they don't weigh on you quite so much. Overall, it's worth playing.
