"The Hyperdimension Neptunia" RPG series has always been as meta as it gets, but the offshoot "Cyberdimension Neptunia: 4 Goddesses Online" takes the meta-ness way out of orbit into entirely new dimensions, hyper or otherwise.
The four bouncy, scantily-clad protagonists, who usually band together, clash and flirt their way along paths to save the universe while satirizing gaming and anime conventions, put the important stuff aside to take part in an MMO. You are playing as gaming characters -- who are well aware they are gaming archetypes -- playing a game that pays subtly mocking tribute to the game industry.
Don't spend too much time sorting through the levels of self-reference or who's controlling whom in what realm -- that stuff will just hurt your brain. Instead, focus on the challenging, "Final Fantasy XIII"-style real-time battles, the witty dialogue and sprightly narrative.
This is a game made for both shameless leerers, as well as those who like to laugh at people like that. There's only a creepiness factor if you take anything that goes on seriously, which is nearly impossible to do.
As absurdly fun as it is flat-out absurd, "Cyberdimension" proves that the series maintains its goofiness along with its gaming bona fides. While not for all tastes, it's an offbeat treat for those willing to give it a taste.
