Off the top of my head:
Miraculum: The Last Revelation (overhead RPG)
Last Imperial Prince (sidescrolling action RPG)
Super God Trooper Zeroigar (shooter)
Team Innocent (Resident-Evil style)
Boundary Gate
Chip Can Kick (Bubble Bobble-style arcade)
Der Langrisser FX (sequel to Warsong on the Genesis)
Return to Zork (utilizies a little FMV, otherwise a graphic adventure like Myst)
Little Red Riding Hood Cha-Cha (board game)
Blue Breaker (RPG sidscroller)
Zenki FX (side scrolling beat 'em up adventure)
..and the list could go on. These are games in my personal PC-FX collection that aren't of the FMV anime genre. Many of those are real gems, too. There are many more that I don't own.
My point is that it's not
quite fair to write off the PC-FX as a simple FMV anime player.
Indeed. It's mostly all FMV/anime games.
If by mostly, you mean more than 50%, then you might be technically correct. But you have to remember there are less than 100 PC-FX titles to begin with. The library is certainly a little heavy on those kinds of titles, but there is a good mix in there of other stuff.
