This game is the full package. It's got some of the best visuals on the console, a really good story for the standards of the series, and a banger soundtrack. All you really need in a Metroid game can be found in Fusion. The only criticism I would place upon the game is that it's level design and pacing can be a little slow due to how heavily gated certain parts of the game are. However, this restricted pacing also plays a large role in the tone and feel of the game, so it's ultimately not a huge deal.
