Prime 2 is my favorite game of the trilogie. Loved prime 1 but I feel it followed to closely the template of Super Metroid. I thought the story of prime2 was more engaging with the Luminoth and Inns and the mystery behind Dark Samus. It also have my favorite guns/visors/suits of the series while prime3 revolved to much around the corruption and the phazon boost gimick for my taste.
Also I loved the Light world/Dark world. Never understood all the hate behind it, It's ok when Zelda does it but everyone goes hating when it's Metroid? What kind of hypocrisy is this? Atleast in Prime 2 I had the ''oh shit'' feeling and felt threatned everytime I was in the Dark world.
Oh, and most important of all, Prime2 had multiplayer and I had a blast with it! Never understood why they took it away in the 3rd game.
