Hmmm ... Let me see if I understand this correctly.
Tetris for the original Gameboy is the #1 launch title of all time.
Halo for the X-Box is #5.
I can't really judge many of these since I've only owned a few consoles in my time, and only played with a few others, missing out on many of the titles listed.
But Tetris? For the Gameboy? And Halo is at #5? I just want to know what the writer was smoking.
