They normally end up in a box in the attic.
But now video game enthusiasts are shelling out incredible sums for hard-to-find retro game cartridges.
It went under the hammer at Heritage Auctions in Dallas, Texas, who have not said who the anonymous big spender was.
Super Mario 64 was the best selling game on the Nintendo 64, and the first to feature the beloved Mario character in 3D.
The record sale came just days after the auction house sold an unopened 1987 copy of Nintendo’s The Legend of Zelda for $870,000.
Valarie McLeckie, Heritage’s video game specialist, said the auction house was shocked to see a game sell for more than $1m so soon after the Zelda game had set its own record.
“After the record-breaking sale of the first game in the Zelda series on Friday, the possibility of surpassing $1 million on a single video game seemed like a goal that would need to wait for another auction,” said Ms McLeckie.
“We were shocked to see that it turned out to be in the same one. We are proud to have been a part of this historic event.”
The only rarer version of the Zelda game is the “NES TM” version, of which it is believed there is only one sealed copy in existence.
Back in April, Heritage Auctions sold a 1986 unopened copy of Nintendo’s Super Mario Bros. for $660,000, which had been left in a desk drawer and forgotten about.
Matthew Payne, an associate professor at the University of Notre Dame, who specialises in media and video games studies, says he is not surprised at the spike in classic video game values.
“While those are truly staggering dollar amounts, it’s not terribly surprising to see those particular Nintendo titles generate such interest,” he said.
“They’re both popular installments in classic franchises with international fan bases.
“Furthermore, as video games are increasingly released as digital downloads, physical copies will only climb in value.”
The price increase of rare games is matched by a climb in the value of all games for vintage consoles.
A study by PriceCharting.com showed that during the pandemic lockdowns, from March 2020 to March 2021 the average retro video game increased in value by 33 per cent.
The largest risers were games for the Nintendo GameCube at 70 per cent, the Nintendo 64 at 43 per cent, the Gameboy Advance at 42 per cent, Intellivision at 39 per cent, Gameboy Color at 36 per cent and PlayStation2 at 35 per cent.
The games with the biggest price increases were mostly related to Pokeman, with the biggest increases in those games that have been graded for quality and boxed.
Games like Pokemon Emerald for Gameboy Advance increased 145 per cent and Pokemon HeartGold for Nintendo DS increased 133 per cent, according to the study.
“Video game collecting became a very popular pandemic past time” said PriceCharting owner JJ Hendricks.
“Game collecting is nostalgic, indoors, and isolated but it also has a big online community so collectors can socially distance while still connecting virtually.”
The study tracked the average game price increase for every major console before the release of PlayStation 4 and Xbox One.
“That $1.5 million price for Super Mario 64 is pretty wild,” added Mr Hendricks.
“All retro games have been increasing in value since the start of Covid. The average retro game is up 51 per cent since the pandemic started.
“Graded games have increased even more though because people are viewing them as alternative investments. Sealed retro games are entering the same league as comics, baseball cards, stamps, and coins as alternative investments.
“As the investment money has entered the market the price for graded games has jumped to new highs. Most investors will only buy graded games because a third party has authenticated the item and because of its condition.”
Earlier this year Gamer.com published a list of the most rare and expensive classic games, which only sell for big money if they are in perfect, shrink-wrapped, never-before used condition.
