Agreed 100%. It was my favorite game on the DS and possibly the best JRPG of the generation (probably loses to Xenoblade Chronicles).
I loved the integration of a grid into the standard turn based combat system and the way you can manage your turns which reminded me of FFX's system.
The story was excellent and the use of time travel/multiple worlds was very cool. Only the Chrono series has done this better.
Every JRPG fan should play this game, especially if you are a fan of the Chrono series. You do yourself a disservice by skipping it.
