Reddit mentions of The Legend of Zelda

You can definitely get this game for around $10-$15. Online at http://www.amazon.com/gp/offer-listing/B00004SVXW/ref=dp_olp_used?ie=UTF8&qid=1311077760&sr=8-13&condition=used or at any kind of retro used game store. $60 is crazy.

I got:
a working NES with Super Mario Bros 1, 2, & 3, Legend of Zelda (gold cartidge), The Adventures of Link (gold cartidge), Dr. Mario - with the original box!, Mega Man 2, and RC Pro-AM Racing
Posable Mass Effect 3 "Minimates" of ManShep, Ashley, Wrex, and Garrus
Figurines of Link from Phantom Hourglass and Zelda from Ocarina of Time
The Art of the Mass Effect Universe
Mass Effect Library Edition Volume 1
"POP!" figurines of Garrus and Grunt
Steam Gift Card (which has so far purchased Mount and Blade Warband and the Ghostbusters game)
Miniature Bat-signal (it works surprisingly well)
Venture Brothers Season 5 on Blu-ray

My birthday is the day after Christmas, does that also count? I got:
A sweet Hyrule map puzzle
Anamaniacs DVD (Season 1)
My friends sBruced up my batroom (or spruced up my bathroom for the pun intolerant) with a custom blue and white batman symbol bathroom sign affixed to my batroom door, a bat-shower curtain, a classic Detective Comics poster to go with my existing Dark Knight Returns (the comic) poster, a bat-toothbrush/utility holder, a bat-soap dispenser, a bat-rug, and a bat-towel (link also features my existing shower curtain holders).

Not sure if this counts, but I also got a kit to make a working ornithopter (I'm a giant nerd for robots and the like). I also bought The Last Unicorn for myself but I think that's probably cheating.

I am quite pleased...I may have yelled "I HAVE AN NES" five or six times...an hour...all day...

There are tons more used ones then new ones now. They don't make it anymore so the only sealed ones left are the ones people bought and never opened, and how many people did that? The older the game the pricier the gap, such as Zelda on the NES

Here's a bunch of classic games on amazon with their approximate prices.
Metroid - $15
Super Mario Bros/Duck Hunt Combo (Duck Hunt will only work on a CRT TV) - $3
Super Mario Bros. 2 - $9
Super Mario Bros.3 - $12

The Legend of Zelda - $20
