Ohhhhhh this explains something that confused me at the time and that I never followed up on. My family had a Nintendo and rented a copy of Tetris, played it for a few days, liked it. Aside from the gameplay, I remembered that they had clear level breaks and interludes where tiny Russian figures danced on the screen. Not that long after, we bought our own copy, and that stuff was totally not there....<p>What is now clear, in retrospect, is that the one we rented was the Tengen version, and the one we bought was the Nintendo release! The year must have been 1989 just as this was all going down.
