[quote name='alonzomourning23']I never even knew arkanoid had any value until today. I saw it listed as rare on a list someone made and then checked ebay, seems to be worth about 50 or 60. I have a mint/flawless one in box with controller and packaging. I figured it was worth 5, 10 bucks tops.
For sega cd, I think the rarest would be koei flying squadron. Snatcher is definately up there. Samurai showdown is another rare one, I've never seen a u.s. one on ebay but the PAL version goes for over 100.
Suikoden 2 isn't very rare, just uncommon with extremely high demand. I've seen discworld a lot in gamestops, I don't think that's very rare.[/QUOTE]
I didn't actually say the games on my list were rare; I tried to pick those I knew were valuable. It's a tough call with older games, too. I bought a disc-only copy of Keio Flying Squadron (not to be confused with Koei, who does all those damn Dynasty Warriors games) for $3 a few years back. Of course, things are worth more complete, but again there's a difference between rare and valuable.
I like to think that Discworld is valuable, because I got so sick being outbid on eBay that I paid a whopping $70 for a mint one.
I'm a huge fan of the Discworld books, currently reading my 26th one.
Let's not forget Cubivore for GameCube, an Atlus game that allegedly had a print run of 2,500. It was so low, Atlus had to get special permission from Nintendo to do it.
