Very well written characters, compelling story with political intrigue.

On the gameplay side, map design is nearly non-existent. I would be hard pressed to tell you which map corresponds to which mission unless there's a boss.

On the tactics side, it's decent enough. The game emphasizes good positioning above other things.
Customization is decent. There's 3 basic classes for each unit, and each of those 3 can branch into 2 upgrade paths.

Overall, I strongly recommend this game.

Also, Saturn best girl.
