Well, it was good, but... there was something bothering me about it.
However.
The dungeon's gameplay system is IDENTICAL, and I mean IDENTICAL to the dungeon gameplay system of Pokemon Mystery Dungeon. It's the same. The little message bar at the bottom, the way Chocobo and his enemies have a turn-based map (everyone has to wait their turn before they can move or attack), the way the map unfolds as you walk through the dungeon... I could go on. I was a bit disappointed with Mystery Dungeon, but it still kept me occupied for a while.
So, long story short, this game is a relatively fun and cute game. If you've never played Pokemon Mystery Dungeon, I would recommend that you don't, and pick up this game instead. Don't get me wrong, Mystery Dungeon was an okay game, but this game is better. If you have played Mystery Dungeon and you enjoyed it, this game is definitely worth your time!
