Is The Yakyuken Special 2 a "good" game? By modern standards, no. It’s a repetitive game of chance with grainy video.
Is it an interesting game? Absolutely. It’s a time capsule. It’s weird, it’s silly, and it’s a perfect example of the kind of bizarre software that made the PS1 library so legendary.
