Another amazing thing is that CTWC (Classic Tetris World Championship) [0] launched in 2010, and still runs, bringing new generation of players every year.
Even more impressive, in recent years those new generations of players found new creative ways to use the original NES gamepads (e.g. rolling) to get to levels that were previously unreachable to humans.
There’s great documentary about Tetris and CTWC: Ecstasy Of Order [1].
