Speaking of Karnov, did you all know, there are only 4 games which have been beaten by a different person every year since this competition started (2012-22)? Karnov is one of those four, along with Bubble Bobble, TMNT Tournament Fighters, and Where in Time is Carmen Sandiego.
Already, BlackVega beat TMNT:TF this year for a second time, so that's off the board, leaving three. mbd39's Karnov completion will ensure that at least one game will continue that streak into 2024.
There were another 30 games at the conclusion of 2022 that have not had a repeat clearer, but also have not been beaten in every year.
