Radiant Historia

The enemies are placed on a grid and your characters have abilities that can move them around or place traps on certain squares, plus as part of the game’s time travel theme you can reorganize the upcoming turn order. Use those together and you can arrange the absolute sickest combos, knocking everyone into a big cluster and then wailing the shit out of that cluster.

Just be sure to play the original DS version and not the enhanced 3DS version with new art, voice acting, and story additions that ruin the tone.
