Great question.
I got MP3 in 2007, but set it aside about 20% of the way in for SMG and never got back to it until recently when I started it all over again.
To answer the original poster's question, I had no problems understanding and getting into the game despite the fact that I hadn't played a Metroid game since the original for NES.
It's definitely one of the best games I've ever played, and I didn't realize that they were making NPC versions of MP and MP2, so hopefully those will come out in the US soon so I can keep enjoying the Metroid series until the next is released.
Now Playing: Pikmin, Super Mario Galaxy 2
