Dracula X: Nocturne in the Moonlight if you want to hit SotN again but with some added features
I was big on Sega CD n still am so the translated Saturn Lunar & Lunar 2: Eternal Blue are decent enough JRPGs for their time. maybe you'd want the un-Working Designs version (undub?) but I haven't tried any of those revisions yet. also Magic Knight Rayearth got a re-translate that I gotta get around to checkn out
Policenauts. Hideo Kojima 1P-Adventure or Point n Click or Visual Novel. somethin like that. definitely a must if you enjoyed Snatcher - but if you haven't played Snatcher it's probably not a necessary precursor required to enjoy Policenauts
Falcom Classics - an Ys compilation. legendary to me - great if you want to try formative action-RPG pioneering
the extra Shining Force III scenario offshoot discs. Tactics Ogre n Sakura Taisen/Wars? or for realtime tactics style try Dragon Force II
I have to go through my stuff to remind me of more to rec' you but I'm doin that for next few days anyway. hope these help for now
