Metroid Prime. There have been amazing games since, but the immersion in Prime was second to none. I've never become 'lost' in a game since.

The Last Of Us. When I bought it, I barely even knew what it was about. I was like "Oh man, Uncharted + zombies".

And it turned out to be one of my favourite games of all time, along with Final Fantasy VI, Silent Hill 2 and Mass Effect. Its story, characters, music, graphics, ambiance, etc... It all blew my mind.

Tropical Freeze.... man that was outstanding.

Bioshock Infinite. It's a FPS that I didn't hate and wanted to dump 10 minutes in.
...awesome game, in fact.

Persona 3

I've played a bunch of great games over the past few years, but only Persona 3 left a lasting impression. It was such a refreshing experience, and I remembered being addicted to that game, playing maybe 4-5 hours straight late at night, telling myself "just one more day." It blended two types of genres to create one magnificent game; being a high school student at day & taking classes, participating in activities, hanging out with friends, etc and then being a shadow hunter & dungeon crawling at night was a pretty fun experience.

Also, the music was catchy, and the story & characters were top-notch. But the gameplay was what won me over. I've been wanting to replay it for the longest time, but I don't have that much free time as I used to.

Persona 4 was also great, and it did fix most of the problems Persona 3 had. However, it didn't blew me away since it was similar to Persona 3.

Knack

It's gripping metaphors for societal injustices and the human condition were subtle, yet remarkably powerful & emotionally moving. I don't think there's been anything to make me feel the way Knack made me feel ever.

Haha, glad she could be of use

Lol

The price point of MGS: Ground Zeroes blew me away from buying it :P
