Hulk is also the only previous console demo I can remember. There have, of course, been numerous PC game demos via DVD-ROM content (Tarzan, The Grinch, Harry Potter, Emperor's New Groove, etc.).
Not that it's anywhere near the same thing, but The Digital Leisure DVD-V versions of those Don Bluth animated "Dragon's Lair" and "Space Ace" games play a lot better on my PS2 than they do on my DVD player, mainly due to the remote.
