Valkyria Chronicles is the best nex gen JRPG by far.
The only English JRPG's that I haven't played are:
- Blue Dragon
- Cross Edge
- Disgaea 3
- Ninety Nine Nights
- Enchanted
From the above I only intend to get Disgaea 3 and Cross Edge, though, CE looks a bit nonsense.
Enchanted arms is ok...I had a copy but never bothered finishing it.
NNN was just a good romp!

You battle hordes and hordes of monsters (and good guys) on a few maps, picking up bonuses and weapons.
The CG scenes are quite pretty and the 7 characters are interesting.

It is a great filler in between games that will probably take you about 10hrs to complete.
The attraction is having your kill count climb into the 1000's on a single map...Oh the joy!
I have Blue Dragon at a friends place.
A very pretty game but it just never grabbed me.
It basically uses the "Job System" for battles.
