While all of the negative points are frustrating, they're nothing compared to playing this game and thinking about what it could have been. With an excellent graphics engine (stuttering aside) and entertaining combat, you'd think that tri-Ace and Square would have a hit on their hands. Instead, it's bogged down by poor writing and some strange gameplay design choices.
If Square were to make a sequel, one would hope that it would hire a new writing staff and streamline the game experience. As it is, Crispy Gamer can't in good conscience recommend Infinite Undiscovery to anyone.
Verdict: Fry it
