Pretty much every one in the video game community, and a bunch of people who are complete aliens to gaming in general, have heard and/or played Tetris in any of its almost infinite iterations; be it official releases, or even blatant rip-offs.
The original Tetris was released all the way back in June of 1984 and was designed by Alexey Pajitnov, as the first video gme to be localized from the Soviet Union to the United States; making its way to the Commodore 64 and IBM PC.
Ever since, the game has become a world phenomenon that it is, even to this day, one of the most recognizable franchises in the video game industry; and for good reason, as its simple, and incredibly fun tile-matching concept caters to pretty much all demographics.
As The Tetris Company celebrates National Video Game Day, they asked Alexey Pajitnov if he ever saw his creation becoming so popular 35 years after its original released. Pajitnov answered by saying that he believes he made a good game and doesn't see a good reason why it should die; revealing that he wouldn't mind celebrating its 50th and even 100th anniversary.
Tetris truly is a game that has gracefully managed to stand the test of time — even after 35 years — with new Tetris titles being released almost on a yearly basis. Obviously, these games haven't always been the exact same version of the original, but all of its gameplay mechanics have remained intact, for the most part — although the original Tetris is still, considered by many, the best the series will ever have to offer.
