I have never played a game quite like Metroid Prime. Definite contender for my favorite game of all time. The sense of isolation and world building is insane, and the Wii pointer controls were surprisingly good. I love how the entire game goes by and not a single line of dialogue is spoken. The scan system is easily one of the coolest parts of the game, and the perfect balance to get just as much of the story and lore as you want.
