Sword Art Online is a young adult media franchise based on a virtual reality MMO.
The recent game debuted at 73k initial week sales which was below the previous game's (Fatal Bullet) debut week of 81k sales.
The game is really poor in various factors (FPS, bugs, load times, etc) so it has very poor word of mouth and will very likely not sell its initial shipment without steep discounts. This of course, has nothing to do with the PS4 but rather has to do with the incompetence of the developer to put out such a shoddy product.
Chris decided to equate it with a fighting game based on a manga/anime superhero property, One Punch Man, which sold 4.5k copies its first week, far worse. I'm not sure why Chris made this comparison personally.
