Very interesting release. The game was quite popular on Vita at the time, but it didn't achieve any success, since Soul Sacrifice was running parallel to it and was much better and more popular as a game.
As a person who once completed this game on Platinum on Vita, I have some doubts about this release. The game has honestly aged very poorly, it is very clumsy with a rather mediocre and boring monotonous combat system compared to its competitors. This is a direct "contour" of the God Eater series, and from the same Namco, but at the same time God Eater is much better in terms of the combat system.
Regarding the length of the game, it is quite normal, something around 30 hours if you just go through the story, 45 hours if you do the side content. The story is not very interesting, and perhaps the main problem that I see is that the game at one time was very much focused on co-op play, and the main emphasis + balance of the game was made on this. And solo playthrough of this game is not very pleasant, if some rebalancing in terms of co-op and solo playthrough is not done in this remaster, I don’t know how long this game will survive in co-op.
This game needs not so much a remaster, but a global rethinking of the gameplay to retain players.
