What is the Single RAREST Item In Your Collection?

[Princess-Isabela]

probably one of the rarer ones - Ninja Masters on Neo Geo AES, worth about $600 or so.
incredible game at that ^^

[Arrrhalomynn]

I'm not sure...I don't really have 1 game that stands out. I do have a few rare ones. Like Alien Soldier for the Megadrive or Street fighter 2, phantasy star and virtua fighter for the sms. I have a bunch of rare games for the Saturn too... Of course all complete.

[Phosphor Dot Fossils]

Power Lords and/or the four Parker Brothers games for the Odyssey2.

[o2william]

Either Pinball for Odyssey2 or Power Lords for Colecovision (both from CGE 2000), or my 2600 Galaxian lab loaner.

Among regular releases, hmm... either Quest for Quintana Roo (by Sunrise) or Tomarc the Barbarian for the 2600. I also have a complete Buster Douglas Boxing for SMS; not sure how that compares.

[Stark]

I'd have to say:

SW Waterworld

Gas Hog

Rescue Terra 1

Robin hood/Sir Lancelot double ender

INTV Demo Cart 1981

INTV Tutankham sealed

[NvrMore]

Hmm I'm still trying to assess the rarity of PAL format SNES games but excluding Proto and other special cart types, probably complete copies of..

Whizz (SNES)
Breath of Fire 2 (SNES)
The Firemen (SNES)
Fun 'n' Games (SNES)

Gurume sentai Barayarou (SFC)

[briskbc]

My rarest would have to be Snatcher for Sega CD

I'm not sure if I should include my 3 multi carts. 2 for the Famicom and 1 for the NES. The NES one has 1000 games on it. Some of the Hacks are pretty funny.

[greedostick]

Dynastic Hero english version for turbo duo

Also english magical chase HU-Card

Gjost Lop MVS cart. Don't know if that really counts though since it was made by a guy who had the original cart and made me a copy from the original.

[Hounder]

About to be Stadium Events with the box. Already have the box, getting ready to pick up the cart, now just gotta find that dang manual

[mb7241]

An update from whatever previous post I might've made...my rarest:

Final Fantasy (MSX, complete) (thanks, Adol!)
Action 52 (NES, complete) (thanks, wberdan!)
Darkman proto (late beta/final) (NES) (thanks, DreamTR!)
Flintstones: The Surprise at Dino Peak (NES, cart-only) (thanks, Goodwill_Hunter!)
Legend of Zelda Collection (Japanese Gamecube, complete)
Team Buddies (this game just seems to find me...seriously...I have two copies, the 4th and 5th different copies I've owned) (PS1, disc-only)
Valkyrie Profile Limited Box (Japanese PS1, complete) (thanks, bleedingblackthornedrose!)

Probably a few more I'm forgetting...

[ApolloBoy]

I think the rarest game I have would be Golden Axe Warrior for the SMS. I got mine CIB about 3 years ago at a thrift store for only $3.

[starfox316]

Chavez II for the snes

[otaku]

Cotton UK for my NGPC and Last Blade best collection are rare from what I hear. I don't own many rare games due to the costs involved but would like to.

[minefield]

Castlevania: SOTN on the PSone

Vandal Hearts on the PSone

Starlancer on the Dreamcast

The Longest Journey on the PC - when it wasn't even released down here yet.

[Trooper]

I don't have any really rare games, closest I get is probably the D-Direct Limited Edition of Segagaga for the Dreamcast.

Flintstones: Surprise at Dinosaur Peak

[ottojello]

I've got three different diagnostic carts for SNES. When I asked a friend what good they were since you couldn't actually play them, he said you can play Super Nintendo Repairmen, so I guess they do count as games.

[The 1 2 P]

Hmm....good question. It could be Snatcher for my Sega CD, Tengen Tetris for my NES, the Japan-only Star Wars Famicom game, Silent Hill for the Japanese GBA, Perfect Dark for the import N64, or Castlevania: S.O.T.N. for import Saturn. Now that I think about it, my God of War 2 E3 demo(taken straight out of the E3 PS2's used) would definitely be the rarest. Too bad it's not a full game.
