Disgea, FF Tactics, or Jeanne D Arc

[Sansui]

I haven't played the psp Disgaea, I understand it's a prequel and not a remake of the ps2 version?

The ps2 disgaea was hella sweet, so if it's on par it would be a great choice. Final Fantasy tactics was also an excellent game, but if you've already played it on the ps1, I'd try my luck with disgaea
