I like both Neptunia and Senran Kagura, so for me this is like the biggest crossover event since The Avengers but better! Story-wise this is a full-on Neptunia game with a couple Senran Kagura cameos, which is fine by me. You either really like or really hate Neptunia games and it's stories, though I was a bit disappointed with the Visual Novel cutscenes. Even the ReBirth games for the PSVita had character models that moved and reacted with lots of expressions, here it's really just a couple jpegs with many lengthy transitions between them.

Combat wise it was fine. Funnily enough this is not the first Neptunia game with Senran Kagura like combat. They already did that with Neptunia U Action Unleashed but there the combat was terrible imo. Here it's competent and actually fun to play. Because here they made a new combat system from the ground up instead of trying to fit RPG elements into existing Senran Kagura combat like in Neptunia U. This sadly also means that pretty much all of the fan-service stuff from the SK games are missing here. No clothes ripping, no questionable camera angles, nothing. This might actually be the most prudent game of both franchises to date!

The game is not that hard, not that deep and not that long but I like it when games know when to call it quits and not overstay it's welcome. This is a 2/5 or 3/5 game for most people but because I'm insane it gets the Neptune bonus to 4/5.
