I have a Pac-Man and Donkey Kong that were given to me as gifts for Christmas when they were actually released. My Pac-Man got beat to hell I played it so much. My Donkey Kong sits on a shelf in my family room, still looks like it was never played... because it wasn't. It was awful.
I may pick up a Pac-Man if the outer casing is the same just so I can replace the broken outer case of my original.
Maybe not. It'd have to be pretty dirt cheap. The games were pretty bad.
