The PS2 era is definitely worth revisiting for Ar Tonelico 1/2 in that regard, also the Growlanser games. Agarest 0/1 are definitely a tough pill to swallow gameplay wise, but I'd check out Agarest 2 - they totally overhauled the battle system and it's quite a different game. You should for sure check out Grandia if you haven't.Yea, we did PS1 era, so pretty sure she's done the whole set - skipped PS2 era with the whole MMO craziness. (Xenogears we've done as well as Lunar not 100% sure on Grandia not ringing bells)
And on Argarest we have it, but really found the gameplay unpalatable (1 I think)
