Suikoden I and II (PS1; PSN) Suikoden V (PS2) Xenoblade Chronicles (Wii; New 3DS; I think Wii U VC) Radiant Historia (DS) or Radiant Historia Perfect Chronology (3DS) Baten Kaitos and Baten Kaitos Origins (Gamecube) Legend of Dragoon (PS1; PSN) NieR Automata (PS4) Exit Fate (free fan-made game available for DL online, runs on PC) Final Fantasy Tactics (PS1; maybe PSN?) Suikoden Tactics (PS2)
Not going earlier than PS1 gen, but of course there's plenty of great JRPGs on the SNES and some on NES and Genesis, too.
Maybe I'm just an irrational fanboy, but I thought Suikoden III was the best of the series and IV was a solid offering.
I mean, I was trying to give a broad sampling of my favorite RPGs across multiple franchises. I agree III is great and IV is still a decent game. I did want to recommend all the main Suikoden games, but figured the suggestion would be brushed off if I didn't pick a few specific titles out.
I want more than any other game, a Suikoden that takes place chronologically after III. I really liked how the plot felt like it was moving towards some sort of final conflict, probably centered around Harmonia, and would like to see a firm conclusion to the various plots. It was also intriguing seeing the antagonists' perspective in the post-game and seeing Leeknat as being more.... "morally grey" than is usually presented.
I always thought, based on that it'd be really interesting as well to have (spoilers only b/c it's impossible to talk about w/o mentioning the spoiler above) a Suikoden II spinoff where Jowy is the main character and he's also being guided by Leknaat to collect his own 108 stars of destiny, because she's manipulating both him and Riou into renewing the fated conflict between their two runes for her own reasons.
That's actually a very good idea for a Suikoden game. Kind of blew my mind there. I think Suikoden fans need to get together and work on the games we want to see come to life. A fan project I think is worthwhile would be remasters, with trophies. Then obviously, games that continue the plot and explore other areas and true runes would be great. ---
