How rare is an autographed Silent Hill 2?
Its signed by the entire senior production staff.
Seems like I have every game mentioned here in this thread. I keep stashes of rare games on the side and sell them years later. I have 4 Intelligent Qubes, 3 Disgaea, 1 rez, 3 Suikoden III ( a suikoden 1 and 2 were put aside years ago and I have to agree that part 2 is really really rare), and a bunch of others.
The secret is not finding rare games...the secret is knowing which games will become rare. All titles on release are available for at least a few days.
Smaller companies tend to make smaller runs. Also watch the Japanese market as it can clue you in to really good games that wont get much attention here...like Rez or Guitaroo. Watch Konami, Atlus, Koei, and CodeMasters...
