Porkies have to spent billions of dollar in researching psychology to create an insane emotion manipulation system in their games to even reach the level of addiction Tetris reached decades ago. Something Tetris achieved by pure good gameplay.
Imagine if the USSR still exist today (:ussr-cry:), we would've seen a game so good we would just straight up fucking dies.
edit: Considering that games from post-eastern bloc countries continues to blow away western and Japanese in the terms of creativity means that this isn't really a joke. :lt-dbyf-dubois: made in the Estonian SSR would send you writhing on the floor speaking in tongues.
Which version was that? The original original Tetris looked like this
Definitely Spectrum Holobyte Macintosh version
First version available in America.
