I always worry when a company touts some visual feature over gameplay. With N3II, it was the number of enemies on screen at once. I think the number was close to a million. It's an exciting idea, but putting that many enemies onscreen at once comes with the unfortunate side effect of less detail and variety. Yeah, you'll see a lot of guys on screen, but they all look exactly the same. I sort of expected this going into the game, but when I began to repeatedly mistake allies as enemies... well, that was a problem.
Unlike the original, N3II falls victim to the "grey skies, grit and blood" school of visuals. I really liked how the original game looked. Characters were bright and really unique. Here, it's the same armor-clad, big sword warrior we've seen before. It's the fantasy equivalent to bald space marines. There's nothing engaging about any of the characters or really anything worth looking at. I'd happily trade N3II multi-tiered forts for Ninety-Nine Nights' lush fields and unique environments.
Music and voice acting get the job done. It's goofy, but I like the overacting just for the sense of personality it injects into an otherwise bland presentation. I only wish other elements were as playful.
