Here are a few English gameplay videos of Hyperdimension Neptunia, courtesy of GameSpot.
Noisy Pixel Explores the History of Hyperdimension Neptunia in Video Series focusing on the game's inception in Japan and its release in the west on PS3.

VGChartz's Adam Cartwright: "Console wars have been around pretty much since the dawn of videogames, but the Hyperdimension Neptunia series makes light of these arguments by personifying consoles and their manufacturers as cute goddesses and has them battle it out for supremacy. It proved to be a sleeper hit for publisher Compile Heart, who after an initially shaky start with the first entry transformed the series into its most compelling franchise."

I (Robin Ek, TGG) just spotted a super sexy cosplay of Neptune from "Hyperdimension Neptunia". Yes, I think it's safe to say that Mikki Monster nailed her Neptune cosplay like a boss.
@Simon_the_sorcerer "Since you got the interview, may one drop you a few interview questions?"
