I've played six games in the Shin Megami Tensei series (okay, just spinoffs except Nocturne), and they've all been awesome. Persona 4 is still my favorite out of those, with P3P, Nocturne and DDS2 following closely.
It's been hard to get pure, oldschool JRPGs on the current generation of consoles. Either they're action RPGs (Demon's Souls, Tales of Vesperia) or SRPGs (Valkyria Chronicles, Resonance of Fate). Fortunately, all those games are great.
[sub]Off-topic: Wish they would re-release Symphonia on one of the HD consoles. Vesperia was too damn good.[/sub]
