Sword Art Online: Infinity Moment is a Playstation Portable game from Namco Bandai, which is sort of an alternate ending to the first half of the anime, where after Kirito defeats Heathcliff, a glitch prevents SAO players from leaving, and the quest to the 100th floor begins anew. Instead of simply having the regular characters who were actually in the anime exclusively, later additional characters appear as well, such as Leafa/Sugu, and Sinon. Leafa is peculiar in that she has her appearance intact from ALfheim Online, despite everyone else (including, amusingly, Sinon) having their real world appearance in SAO.
Infinity Moment is a third person RPG, and at current is only available in Japanese. It is relatively playable for someone who has no ability to read Japanese, as a good deal of the text is in English, or easily decipherable. With judicious saving and a lot of experience in several similar games, the English speaking gamer can indeed play through this with only a little difficulty. However, since this is from the perspective of western gamers, the usual pro/con list will be reflected as such.
- Sword Art Online! While patently obvious from the very title, this is a Sword Art Online game. You get to play as Kirito, hang out with Asuna, Lisbeth, Silica, and the gang. It's a fun world, and one that most people who play the game will already be familiar with and enjoy. This fact is a big head start on making it a good game.
- Long. While a lot of 'tie-in' games are short and don't feel like you get your money's worth, Infinity Moment is rather lengthy. A fairly complete playthrough should take in the neighborhood of 22-25 hours. For a handheld rpg, that's pretty good! This rivals even some console games, though is dwarfed by sandbox style console RPGs such as Fallout or Skyrim.
- Playability. This game is pretty accessible. The controls are intuitive enough that they can be figured out without speaking the language. The skill menus work easily, and the icons for skills and powers are distinct enough to not need much more to go on.
- Voice acting. As you might expect from a video game of a popular anime, the voice acting in Infinity Moment is simply top notch. Even for things as little as Kirito exulting when he levels up, or your squaddie yelling for you to be careful around a tough enemy, the voice-overs are quality material.
- Multiple Endings! There are in fact seven different endings to this game, which are really only reflected by the ending cutscene. There is one 'generic ending,' and six 'character' endings, which become accessible after you complete that particular character's quest line. As you can do all of the quests in one playthrough, you can essentially pick which ending you want. Mostly the different endings have to do with who Kirito hangs out with and shares some quality time after beating the game. Asuna's ending could be considered the most 'canonical,' though since the entirety of the game is an alternate retelling of the anime, it's a bit of a moot point.
- No English. Not a negative of the game per se, it is in Japanese, and while, as mentioned before, it is still navigable for someone who speaks English, extra caution is advised. While many important messages are in English (such as level ups, thankfully), some important pieces (such as item names) are solely in Japanese, which makes equipping Kirito a mite difficult.
- On screen text. There's so much status text going on screen at some points that you can't really tell what's going on. Fortunately, most of this is during animation sections, so there is nothing you need to be doing anyway, but it can be distracting.
- Repetitive. This is sort of a hallmark of this type of RPG, but the enemies and bosses get recycled a lot. Combine this with the fact that most enemy AIs will not move to fight you, and is boils down to a lot of 2-on-1 fights. Essentially, you can pick your battles, and spam Kirito and Asuna's tag team attack to wipe the floor with most enemies.
Infinity Moment is a lot of fun! Despite some odd hang-ups in the gameplay, it runs well and is free of most of the glitch and bug issues you find in video game RPGs (including, amusingly, the one in the story!). For fans of SAO it's worth a look, though you need to be ready and patient to deal with the language barrier.
