Judging by the reviews hitting today on Ninety-Nine Nights, I'm one of the few people who seemed to like the game. That isn't to say I don't think it has issues, but I still found it a lot of button-mashing fun.

There are a few drawbacks to the game, such as the fact that it doesn't take to long to beat it in the first place, I was able to complete the game in less than a week, and the formula of the game, while a bit more expanded than past Phantagram games, still feels very similar.
Score: 8/10

On paper, the multiple characters and item collection might make Ninety-Nine Nights sound like a reasonably deep action game. Unfortunately, the action starts out completely mindless and wears even thinner as time goes on. Whether you're a fan of the let's-see-how-many-guys-we-can-cram-onscreen genre or not, this one's probably not worth your time.
Score: 5.9

Honest Gamers
Ninety-Nine Nights is grand, sweeping, and epic. Each character's attack style is varied (the vengeful priest is particularly fresh), each storyline features different twists on familiar missions, and the secret character's adventure is a BLAST. At the best of times, the game's thoroughly engrossing and a joy to play. Unfortunately, because of numerous design issues, it can't fend off the bellowing swarms of other, better, older brawlers.
Score: 7/10

Games like N3 are to video games what Die Hard and the X-Men are to movies: Just plain fun.
