Right now I'm enjoying Shadow Hearts Covenant a lot and honestly there's something 6th gen about it that makes me enjoy it more than most of the 7th gen JRPGs(and I've played lots of 7th gen JRPGs).I guess it's a combination of it's creative story setting,the way it's towns look and the way it's battle system is and the way it's cinematics don't try too hard to flaunt the PS2's graphical capabilities and instead focus more on being artistic and give a beautiful dreary atmosphere with beautiful use of shades of yellow for it's lighting but it has enough technical realism to give a nice real world feel.
Not long ago I beat Fire Emblem Awakening and even though it's technically an 8th gen system,it's visuals are a mix of 16-Bit and 6th gen quality visuals and I loved it's in-depth story telling for the game's characters and turn-based system.
Earlier this year I beat Ni No Kuni on the PS3 and even though it's an 7th gen game,it feels like a SNES/PSone JRPG because of it's charm and because of how it's world map is set out and the way it lets you visit towns and interact with NPCs.
Final Fantasy VII Crisis Core is one of my favorite games of all time and is a PSP exclusive and even though techically the PSP is a 7th gen console it's basically a handheld PS2(PS2 is 6th gen).
Lost Odyssey is one of my favorite games of all time and even though it's a 7th gen game,it's style is much like a 6th gen JRPG(which is part of why people criticized it).
I can't wait for Final Fantasy X HD(a remake of a 6th gen game and my favorite game of all time).
Even though FFXIII,Demon's Souls,Valkyria Chronicles,Resonance of Fate are great and innovative 7th gen JRPGs,I still prefer many 6th JRPGs over these games.
Many people bought Persona 4 The Golden which is a remake of a 6th gen JRPG.
Some people say Star Ocean The Last Hope reminds them of the PS2 JRPGs and is why they love it.
This is why after I beat Shadow Hearts Covenant I'm going to finish Tales of the Abyss and then I'll move onto Wild Arms 4 and then Paper Mario Thousand Year Door.I'm even tempted to buy a Wii U simply to play Zelda WindWaker,one of my favorite action/adventure games ever to be released,which was released for Gamecube during the 6th gen.
