Granted, this isn't just any Tetris. It's an original Japanese Mega Drive Tetris cartridge in like-new condition. I can see that you're still not reaching for your stack of credit cards. Let's sweeten the deal. The case is also signed by Tetris creator Alekséi Pázhitnov.
A seller in Spain going by the eBay handle "shinsnk " is auctioning this extremely rare version of Tetris. His ad claims that only a handful of the cartridges are known to exist around the world. Better go check the boxes of old video game gear in your closets, folks.
You may be able to skim in at a more bargain price. The seller is accepting offers below $1 million but says he has already rejected two offers of more than $17,000. He admits in his listing that he paid about $16,000 for the game just four years ago, so he's looking for some return on investment.
The outrageous price tag is a good gambit for drumming up interest in the auction. If the nearly $50,000 offer in the questions-and-answers section is real, then it may be working.
The seller does have impeccable feedback, so you can rest easy knowing that your $1 million Tetris cartridge will be delivered, as promised. It's cheaper than a Picasso, but much less likely to impress your friends and family. If I were you, I'd go for the Jag instead.
