Amazing game with a lot of combat depth. On lower difficulties, the game doesn't really force you to go TOO in-depth, but even on the standard difficulty the game definitely slowed down a LOT for me once I got past the first 3 areas just because there was so much to do with my units to organize and customize them as they got more skills and more AP/PP to use them. Unfortunately, you can kinda tell where they ran out of money (because Vanillaware) starting in the last main area, and the unfortunate lack of post-game shows it. But, at least there's some online PvP, even if you can only fight so many times per day.

That said, 2 legit flaws
1. While the character-writing is solid and way-less obnoxiously trope-y than Fire Emblem, especially the modern FE, the main character and his closest friends are utter cardboard. You can kinda forget how boring they are and get absorbed in the game, but come endgame the story sequences drag, being generic and predictable as possible.
2. Cavaliers not being the leaders of most of your units is almost always a mistake. Even when facing units that counter Cavs, they're still strong characters, and as leaders they're just twice as fast as any other unit. Which you can make up for with a skill that boosts movement speed, that makes the Cavs even just that much faster than the units that are on-foot. You don't really need to do this, but it's such a stupid advantage (especially with how it removes the time limit from ever being something you have to consider) and navigating the battle maps ends up feeling so slow without them. This removes a lot of the interesting decision-making around which character leads your units.
