If the $8 million price tag for the T-Rex iPad was a little too rich for your blood, then maybe you would prefer to place a bid on eBay for a $1 million copy of Tetris for the Sega Mega Drive, better known stateside as the Sega Genesis.

What makes this particular "like new" copy so valuable is its rarity – only a handful are known to be in existence – and the fact that it's signed by the game's creator, Alekséi Pázhitnov.If six zeroes are more than you can handle, feel free to throw in an offer and hope for the best.
