I agree. I had the pleasure of seeing a Coin-Op Tetris (the original too!
) at an arcade in Daytona Beach, Florida that was located underneath a human sling shot ride. Unfortunately, it was out of order.
There's an establishment in my corner of the globe known as "Barcade" which is exactly what it sounds like; a bar, and an arcade. All games are 25ยข a piece, and amongst them is a Tetris machine. They refuse any games beyond 1989 (they turned down both Mortal Kombat and Street Fighter II). They keep everything in awesome condition, and serve awesome beer, and last time I was there, I got #4 on the Tetris Machine.
