Serious talk...
If ANY of these JRPGs got a remake or sequel, I'd be over the moon:
1) Shadow Hearts - The mix of horror and humor, of such a charismatic cast, of goofy fun mixed with gut-punching sorrow. When Covenant came out, it was the first JRPG that made me look at what Square Enix was doing and realize that a new JRPG had beaten them at their own game.
2) Skies of Arcadia - Storm the enemy fortress, fight the smug boss, rescue the girl, and fly off in your airship. I remember thinking the climax of any other JRPG was the INTRO to this one. Now, with games like Xenoblade Chronicles X and Final Fantasy XIV showing off how to do flight and exploration, the idea of a modern Skies of Arcadia makes me salivate.
3) Panzer Dragoon Saga - This is a lost game. One of the greatest JRPGs of all time... trapped on the Sega Saturn, the code for the game apparently lost, and used copies selling for the price of a kidney. That setting, though... that music. It's what I imagined a Nausicaa game would look and play like.
4) Legend of the Dragoon - Ah yes, the "Final Fantasy 7" rip-off that was nothing like Final Fantasy. While it had its problems, the game still blew me away. The rotating cast of characters, the legitimately shocking deaths, the power-ups and Dragoon forms, the challenge, the soundtrack and visuals, the jaw-dropping background lore and cutscenes... This is one highly underrated game. I want a remake or sequel just so the few things it did wrong could be addressed, because it does so much else right.
5) Lost Odyssey - This was my favorite traditional JRPG of last gen. It was also on the wrong platform. While Microsoft helped publish it to "win over" Japanese players, it just didn't work and was ignored. That's a travesty and I'll go to my grave believing that if it had been on PS3, it would have ushered in a new lasting, beloved franchise. It was such a great Japanese RPG but is forever stuck on a system Japan avoided like the plague. Even a PC port at this point would be better than this fate.
6) The World Ends With You - UGH. SQUARE ENIX.
