Limited Edition versions of games have been around for a few years now. They are particularly popular in Japan. There are several DC games that come in both regular and limited edition versions. Some that come to mind are Dead or Alive 2, Shenmue, Border Down, Fire Pro Wrestling, Biohazard Code Veronica and Shikigami No Shiro 2.
Another recent LE is Robotech Battlecry - LE for the PS2. It came with figurines and artwork I believe.
Dont forget Sonic.
