One of the greatest inventions to date.  The Namco II plugs directly into the AV input of your TV, and run off of AA batteries.  Totally portable!  This version includes the arcade originals Ms. Pacman, Galaga, Pole Position, Mappy, and Xevious.

The Namco I is every bit as awesome as the Namco II, and you can't have one without the other.  This version also includes 5 classic arcade style games:  Pac Man, Galaxian, Rally-X, Bosconian, and Dig Dug.  These games really bring back the memories!

The Namco Museum is available for all console platforms, from N64 to the X-box.  This is another true to the arcade game anthology, including 6 great classics:  Pac Man, Ms. Pac Man, Galaga, Dig Dug, and Galaxian.  There are different volumes too.

Show your retro spirit with a classic Namco t-shirt, like this Pac Man t-shirt that features a ghost and the caption "Eat Me."  This isn't the only version, there are many more.  Not only are there tons of shirts available at Amazon, but at eBay as well.
