Circa: 1990 

Nintendo’s 8-bit handheld set off the portable gaming movement and had every child wishing for one under their Christmas tree every year. The ability to play new titles like Super Mario Land and Final Fantasy Legend, along with popular NES ports kept us glued to the huge slab of gray hardware on the go. And if there was any game that could sum up our '90s childhood best, best believe it's Tetris.
