Actually it's true, most RPGs in general are turn based. The turn based RPGs for PS1 that jump to mind are Legend of Dragoon (people liked it, I have no idea why), Dragon Warrior VII (actually the best selling PS1 game of all time), the Suikoden series, Final Fantasy Origins, erm... Was Wild Arms turn based? I never played it.

As far as ATB and similar systems, I'd mention the Final Fantasy games, Xenogears, Vagrant Story, Star Ocean 2, and I guess that's all I can think of. There were a few more RPGs released around the time that FFVII came out than usual, but that died off soon enough.
