Next to Super Metroid, Prime is one of the best games ever made. It's rare that a game can be fresh and innovative while simultaneously so perfectly executed, all while standing the test of time in every regard.
Despite the realistic art style, the graphics are still beautiful all these years later, with so many great details that even other games today have not included so well (the visor effects, such as Samus' breath fogging it up, the reflection of her face/eyes when hit with a flash of light, the patter of rain drops on the surface, add so much to the immersion). The music is a wonderful new take on the brooding alien atmosphere of past games. These components culminate in a unique style that hasn't been captured by anything else since.
From a gameplay perspective, Metroid Prime also accomplished something bold. They successfully translated the Metroid formula to the FPS genre, expanded on it with features like the scan visor, and stuck the landing on making a platformer that really worked in first person.
If you haven't played Metroid Prime (or the rest of the trilogy, for that matter) do yourself a favor simply as a person who appreciates the medium; you won't be disappointed.
