Neptune has an alternate dimension counterpart who's a regular human girl (the one in the black hoodie) and looks older despite being younger than the regular Nep. There's also lots of clone consoles out there, happens like every other game.

It's my favorite JRPG series, which means a lot (or nothing) because I hate JRPGs with every fiber of my being.
Would I enjoy it without Neptune? Hard to say, she's very central to the game's identity, being the main character. I do enjoy the world and the other characters are all great too but Neptune being there is just what makes Neptunia itself. Still, I had a decently fun time with the two games that don't feature Neptune prominently (mk2 and SVS) and the time they give the others the main character spot during a chapter, I'd have enjoyed the games but not think nearly as highly of them, and would have probably never remembered them after playing. A game with Noire as the MC sounds genuinely misserable, god.

The sound effect when an enemy dies in the Rebirth games is always satisfying.
