Although the concept of it being in a Sonic game was pretty silly (and an entire path to play through no less) and the character is really annoying, I heard that even the Big the Cat fishing mode in Sonic Adventure (originally on the Dreamcast) was even good, gameplay-wise. I have played it but I don’t have much experience in other fishing games to compare it to. The only other fishing (mini-)game I have for comparison is the fishing in the 3D Zelda games. Between the two I think I prefer Zelda, though.
