Sakaki affirmed Kaorin's assumption of her playing the vidya once, and being kinda good at fighters and racing games, but that could've been a white lie to keep her crane game winnings a secret.
Still, I'd imagine Kaorin would've been even more awestruck after discovering Sakaki's crane skills. Winning those things earns you all kinds of bragging rights, no matter who you are.
I'd kinda like to watch a moment of Sakaki teaching Kaorin how to play those games, like how she wanted.
Also we got the manga confirming Yukari being in possession of a PS1, I wonder if she's a fan of Twisted Metal…
