I've probably spent over 200 hours with this one. I was addicted. It got so bad that my brother and I brought our GameCube to our grandparents house to try to unlock Roy. My friends and I brought Gamecubes and memory cards to each other houses and had about a billion sleepovers because of this game.
Crazy addictive.
Playing Portal 2 is constant enjoyment. There was never a moment of unearned frustration or annoyance. It's perfect. Not near perfect, not "nothing is perfect" perfect, it is pure perfection. It is the game I would show someone and proudly proclaim this is my hobby.
A flawed masterpiece, but a masterpiece nonetheless. A towering and effective blend of atmosphere, music, voice acting, story, character, and imagination that defines the videogame medium better than almost anything. I will never forget the first time I walked the haunted halls of Rapture. Or the second time. Or the third time. Or whatever number playthrough I'm currently on when you're reading this, because BioShock is one of the few single player games that consistently compels me to revisit it.
The best.
Even though I saw the whole story unfold on the ER, I was still totally immersed in the world of P4.
Call me the Russian Mindbender.
Even with its flaws I love Fallout 3. All the little stories that could be found in the Wasteland made it incredible.
Fun ass game with great personality.
Specifically the N64 version.
