There's a Sega Genesis of questionable working order at my mother's, as well as two Nintendo 64's and Playstation 1's (one each here with my father and one each with my mother). My Playstation 2 is still working, though the controller has some wiring issues. I also have such gems as The Final Fantasy Anthology, FF VII, VIII, IX, the XII Special Edition, The Legend of Dragoon, Okami, Shadow of the Colossus, Devil May Cry, and Kingdom Hearts I & II.
I have the entire Scrubs series on DVD (save the 9th season because I consider it to be in a different technical series).
I have two copies of
The Lord of the Rings books,
The Chronicles of Narnia, the
Harry Potter books, the first four
Artemis Fowl books, the six
Seventh Tower books, and the first ten
Redwall books.
And while not my own, my father has the entire DVD series of Stargate SG-1, Firefly, The 4400, and M*A*S*H*, VHS tapes of the original Star Wars and Star Trek films, and the following books:
The Chronicles of Narnia, First Collier Books Edition -
The Silmarillion, First Ballantine Books Edition -
A fairly large number of Isaac Asimov Foundation and Robot books, and
The original, first edition hardcover copies of
The Hitchhiker's Guide to the Galaxy;
The Restaurant at the End of the Universe;
Life, the Universe, and Everything; and
So Long, and Thanks for All the Fish.
He actually has far many more books than that, but those are the ones I personally find fascinating.
