Just because video games are fun doesn't mean they can't mean serious business.
People are willing to pay a hefty price for nostalgia and one-of-a-kind releases, and thanks to retro gaming website RacketBoy, you now see just how much.
From golden Nintendo cartridges to games that let you play as an 8-bit Moses crossing the Red Sea, we've tabulated the rarest and most expensive games of all time.
Spoiler alert: People love rare Atari games.
15. "Elemental Gearbolt" Assassin’s Case (PS1): $1,400-$1,750
"Elemental Gearbolt" is a Japanese sci-fi shooter released for the original Playstation in 1997.
The Assassin's Case was awarded during a 1998 E3 tournament, and only 40 of these limited-edition bundles were produced. The case includes the "Elemental Gearbolt" game and a golden "GunCon" and memory card.
14. "Eli’s Ladder" (Atari 2600): $1,500-$1,700
"Eli's Ladder" is the rarest educational video game in existence.
Players answer simple math questions to move Eli up the ladder and into his spaceship, all so he can fly to the moon. The game even includes a wall chart and motivational stickers, according to RacketBoy.
13. "Karate" (Atari 2600, Ultravision release): $2,500-$4,000
"Karate" for the Atari 2600 was designed by black belt Joseph Amelio. The game was actually released by two publishers, Ultravision and Froggo.
The Ultravision version, released first in 1982, is far more valuable than the Froggo release, though the games are exactly the same.
