I didn't play this right when it came out. I had a lot on my plate grad school-wise so I put it on the back burner. To be honest, I hadn't followed it that closely since I wasn't really thrilled with MGS2 so I told myself "meh, I'll wait a little while to play this one." Plus I was still exhausting GTA:SA and Metroid Prime 2.
I remember perusing the video game section of Best Buy post-Christmas, and saw that it was out. Although I was soured on MGS at that point, I had finished the GTA and MP2, plus the GAF/internet reactions and a 50 dollar gift card prompted me to buy it.
I had (begrudgingly) agreed for plans to go out on New Year's Eve with a few of my friends to some crowded bar; one of those pay-a-shitload-to-spend-the-night-with-people-you-don't-know-or-care-to-know New Years Eve celebrations. The morning of NYE was also my first full day off from my part-time job and I decided to pop MGS3 in the late morning or so. I remember my cynical attitude and naively thinking to myself "oh this won't be nearly as good as the original, and will likely fuck up the story even further than MGS2." The splash screen comes up, and I'm waiting for some sort of intro video/trailer to the game... but alas, it doesn't come. Already preparing for disappointment, I start my playthrough of the Virtuous mission.
The Virtuous mission took me about 1 1/2 - 2 hours, and I was starting to really get into the gameplay and story. Then the Virtuous mission ends and there's the cut to black... then the credit sequence for Snake Eater with the Cynthia Harrell vocal theme begins. At this point, I was floored by the realization that I had played what was the equivalent of the opening 10 minutes of a Bond movie and I remember audibly saying "holy shit," alone in my apartment.
The rest of that New Year's Eve was devoted to fully playing through that game, and exploring every single nook and cranny. I remember calling my friend and telling her some half-hearted "sorry, not making it to the bar, have fun" lame excuse, but there was more MGS3 to play. I finished the game shortly before midnight, and I just sat there trying to absorb the impact of the ending, and slowly realized I had played one of the best games of my life.
I've revisited the game a few times and I still love it, but I don't know if I'll ever have as perfect a moment of game playing as I did that New Year's Eve.
