Lord, they have those in my mall. Supposedly they have "72,000 games in one!!!", but as far as I can tell, they just repeat the same 20-odd titles over and over again, and just give them different, and weird, names.
And it's not even that good quality. It has Tengen Tetris in it, but none of the buttons rotate the blocks. Super Mario Bros. runs almost twice normal speed, which gave me a good chuckle. I laughed even harder when the guy told me it would cost almost eighty bucks.
I wonder if they'll still be there next weekend.
