The story starts out with the Neptune and friends playing "4 Goddesses Online" and they begin to notice the existence of new characters, and then proceed to fight enemies. Also, there will be an enemy who is similar to Arfoire.
While it can be a grindfest, fans of the CPUs will want to check it out just to see how often Noire is referred to as having no friends.
Cyberdimension Neptunia: 4 Goddesses Online is a game that fans of the series will enjoy. The dialogue-heavy nature and comedy are well done, and the story doesn't get in the way of it. It does a serviceable job of making the MMO-style gameplay work, but you have to accept the grind in order to not be bothered by it. It isn't a good title for those...
Honestly, were it not for some really glaring problems, such as the AI's problems with ledges and the poor gear balancing, the game itself would be pretty fun.
There ends up being a lot to unpack about Cyberdimension Neptunia: 4 Goddesses Online, but to compare it to any other title out there on the market wouldn't be adequate preparation for those who are deep-diving into the series for the first time.
Cyberdimension Neptunia is a decent action RPG, meant for the fans of the series to kick back and relax with.
