Topic: what's the rarest game you have?

Does the original Metroid Prime 3 count? Or maybe Pokemon Firered?

Tengen Tetris.

We have a winner.

Mine would probably be Chip N Dale Rescue Rangers 2. Not sure if that counts as rare but I know it fetches a high price on Ebay.

Conker's Bad Fur Day is a rare Rare game, right? I own the cartridge for the N64.

Nothing that rare. I think the rarest I have is Harvest Moon 64, or maybe Klonoa for PS1.

I do have all Mario Party games for N64 as well. Maybe they are rarer because is the full set?

I think some people are reading the title and original post wrong. I don't really know I have anything that is rare since I do not plan to sell my games in the future. I just realize that Club Nintendo Game & Watch Collection might be rare game. I have both 1 and 2. (I wish the Pinball haven't been sold out.) So I probably don't have anything that is rare. I just guessing that Game & Watch Collection are probably the rarest thing I have.

I've got that Zelda Collection for the Cube. Didn't know it was rare.

Hmmm I'm a big collector of comics and action figures but don't collect games as much, due to the fact that most games that I care about will eventually make it to virtual console. I sold my Zelda: Link's Awakening DX still in its box a few months ago and made a killing! Still, nothing will ever make me sell my Snes collection They're not particularly rare but most are still boxed. (Yoshi's Island is my pride and joy!)

Legend of Zelda collector's edition (GC)
Tingle's balloon fight (DS)
Game & Watch collection 1 (DS)
Game & watch collection 2 (DS)
Metroid prime hunters: first hunt
legend of zelda four swords anniversary edition (rare now since you can't download it) (DSI ware)
Donkey kong original edition (3DS vc)
Tetris party live (rare now since you can't download it) (DSI ware)
and maybe grill off with ultra hand since you really can't buy it right away, other then that the games above are either rare or just became rare.

Very mature.
The thread's title isn't "rare games you own", but "what's the rarest game you have?", so anybody is elligible to post his or her rarest game here, since every owner of video games obviously has to have a game that is the rarest among those.

As for me, it's got to be one of these:
Starcraft 64 (Australian PAL version), Snowboard Kids 2 (Australian PAL version), HSV Racing
Twilight Princess trailer DS cartridge given to me at the Nintendo E3 press conference 2005
The Kirby e-reader prize card from E3 2002
My sealed copy of Ocarina of Time (sealed by Nintendo, complete with their red seal, not some cheap foil anybody could wrap around a game)

The games I listed are very rare

but now I don't know if it's rare anymore....

horse duuuuuuuuuuuuuuuuuuung

I have Jurassic Park Operation Genesis for the PC, which goes for upwards of 80 bucks.

Some people seem to confuse "valuable" for "rare".
Even if games like Conker's Bad Fur Day, Paper Mario (both the first and second), Xenoblades, Ikaruga, Mario Party 2+3, Secret of Mana, Chrono Trigger and even to some degree Earthbound have been rising in price, that doesn't mean they're rare. Most of them can be found with ease and are on sale just about all the time.

Rare is stuff like Tengen Tetris, Clayfighter Sculptor's Cut, Stunt Racer 64, the Ocarina of Time Special Edition (not the US gold cartridge one, but the European big box one. It was released when just about nobody cared about special editions, but now it's extremely sought-after, and most people don't even realize it exists) or some stuff that I am lucky enough to own:
The Twilight Princess trailer on a DS cartridge given out at E3 2005. Only a few hundred of these had been given away at the press conference.
The Kirby e-reader card from E3 2002. Once scanned in at E3, they were destroyed, which is why only few are remaining.
The Extreme-G Special Edition with an official soundtrack CD.
The PAL versions of Starcraft 64 and Snowboard Kids 2. Even the US versions are fetching neat prices by now, but the only PAL versions are the Australian versions, with supposedly only 5000 units produced.

xenoblade, mother 3

Lagoon (SNES)

I own The legend of Zelda skyward sword limited edition with the golden wii mote and sound track. but its not rare its just that its limited edition that makes it really valuable.

On PC, Theme hospital

but easily would have to be megaman legends 1, 2 and the misadventures of tron bonne!

Is any of the e-reader cards rare?
