You wanna true mindbleep?
Try running the ORIGINAL Tetris on anything 386 or faster...
Yup. I'm talking about the one that came out when the 8088 was still going strong.
On faster computers, it runs faster. On today's computers, game over before you react.
Some of the early Sierra games will do that, too. You need to run something that simulates a slower clock speed, or your character turns into The Flash the first time you try to move.
