When it comes down to big Action RPG that really destroying be on the PS1 back in the mid 90’s one of the top titles that comes to mind is Seiken Densetsu 3. While its pretty cool that Square Enix decided to make this game an SNES exclusive Seiken Densetsu 3 really could have shined well on the PS1. Around 1995 the PS1 has began to increase in popularity and more people began to prefer the 32-bit console over the 16 bit SNES. Also, many might find it puzzling why Square Enix had never released Seiken Densetsu 3 in other countries such America and the United Kingdom for the SNES or even the Nintendo Switch.
Some can make the argument that Square Enix was afraid that Seiken Densetsu 3 would have been over shadowed by many big 3D titles for the PS1 back in the mid 90’s such as Tekken 2, Crash Bandicoot, Resident Evil, Tomb Raider and others. But on the other hand Square Enix decided to re-release 2D Action RPG titles such as Chrono Trigger for the PS1 in 1999. So its tough to say why Seiken Densetsu 3 never made it to the PS1 back in the 90’s.
