A video game that you become enthralled with to the point where you sever all ties with family, friends, and even food to play, because it is that amazing.
I for one have spent a lot of time playing video games, and I have to say, no two games captivated me like Grand Theft Auto 3 and Vice City. I devoted months of time over those games, they were all I could think about. And all the controversy over the game's content made me love them more, I could drool. So, my vote would go to the GTA's any day nad twice on Sunday.
