Don't listen to these guys. It's an awesome game. I haven't played Makai Kingdom, but out of Disgaea, La Pucelle, and Phantom Brave, Phantom Brave is the best.
The battles are really great. They get really creative with them. Like boss fights where you can't hurt the enemy and have to figure out a way to kill him. Or one where you can't bring in weapons and have to use only the stuff you find in the map. And speaking of weapons, you can use normal stuff like swords and axes, but also pretty much anything on the field can be used as a weapon. Flowers, trees, rocks, treasure chests, watering cans, starfish, skulls, all kinds of stuff. And along with all the goofy weapons come themed skills to match the items. Like treasure chests will have you attack with money, mine carts will have you run over the enemy.
And a lot of people hate how your party members are only in a battle for a few turns before they disappear, but it gives the game a feeling of speed. You can't waste time, so you're always moving and trying to finish a stage quickly and efficiently. It makes FFT feel like a chore in how long it takes to do something. Press o, move cursor to where you want to move, press o again and 20 button presses later you've moved. Here it's move cursor to the guy you want to hit, press X and the character will automatically plot a path and hit him for you.
The story's good. I don't really care about stories in games, especially SRPGs, because lets be honest here, most game stories suck. If you play video games for stories, i lol at you. PB's story is really sad at the beginning. People are so mean to cute little orphan Marona that you feel really bad and you wish she'd use her powers to get revenge, but she just takes it and turns the other cheek.
So yeah, it's easily worth $20.
