Whatever, I'll double post my impressions since no one else has been in--
Overall, the game is great, though no without flaws, but the localization is a bit worse, almost certainly due to IFI doing it instead of NISA.
Basic gameplay is ripped straight from Neptunia Victory, with good reason.
The Remake system basically replaces the Scout and Plan systems from Victory; no more silly sending scouts and playing dungeons, no more random chance to get access to Risky Foes or Item Change. A lot of unnecessary randomness was taken out, which is extremely good. However the remake system requires "MB", of which there is a limited amount in one playthrough. The problem here is there's zero challenge in a New Game Plus (there never has been in HDN), so going through for more MB is completely mindless and they really should focus on cramming in postgame content to unlock MB instead. MB is mostly a problem if you want to unlock the CPU Candidates/sisters, they require at LEAST one extra playthrough.
Graphics are quite good--some low-res textures on maps but...they were pretty rough in Victory too. Framerate is great except immediately after loading an area. Only thing that really stands out is Vert's HDD form, some pretty ugly pixels going on in the chest area texture. I'm amazed that passed QA since, you know, half her skills shove her chest into the camera.
There's only 2 endings, activated only upon finishing the final boss, and there's no way to lock yourself out of either one--something I wish future titles would emulate. Mk2's endings were a pain, and so is Victory's highly variable length due to which ending you're targeting.
Trophies are mostly good and not too grindy, except the "billionaire" one which is awful. Also, it requires 100,000,000 credits, it's actually apparently a typo the localization preserves. After going out of my way to unlock every dungeon and beat all Risky Foes, I'd estimate I had about 10 million credits tops, that is a LOT of unnecessary grinding. All other trophies were earned with little effort, accidentally or simply by leveling (I was 100 before starting NG+ just by beating one or two of each risky foe).
DLC is a mixed bag--the DLC characters are extremely charitable at a buck a pop. Plutia is...just plutia from Victory. Great character, dub is a bit worse, not bad. Still does damage like mad and builds unfair amounts of EXE gauge. Peashy kinda sucks, almost no skills, her normal form uses Nepgear's voice clips, generally not very good aside from her one skill.
Lily System seems a bit broken in this one. People that fought together for two playthroughs have a lily rank of 1. Others have 6. I have no idea why. IMO, after 2 playthroughs like everyone should be at max. Doesn't really matter too much though, just odd.
Histoire on the other hand is a superb addition. Her dialog is mostly great, though the "why me?" line is lame; almost all of her lines are badass but she occasionally says "why me?" with a normal attack. Compared with "You will burn" and "I will erase you from the annals of history!" it's pretty out of place. Her skills are pretty good, her EXE attack is awesome, and she's got great animations too. Very impressed for a $1 non-recycled character.
Now, the localization--it's acceptable, but extremely light on dubbing after the first chapter. It's been a problem with NISA localized titles too, but I think Rebirth has the least. Some very silly errors are present, including a second map icons incorrectly named "Dongkong ruins". There's some odd lines as well, but not too many. Mostly my problem is the low amount of spoken content, and the fact that Noire and Blanc sound worse. Blanc has absolutely no punch in HDD form, she doesn't even sound mad, she also hilariously mispronounces zerstörung as "zerstrong".
Combat dialog that's identical to Victory has been rerecorded, and almost all lines are a bit worse. Blanc isn't mad, and her untransformed form sounds a bit lame. Noire is whiny, rather than haughty--loved her voice in prior games but it's mostly whiny teen (more like Uni) in this one. IF, Compa and Neptune are fine. Vert's about the same. Plutia's lines, especially transformed, are a bit off too. She's just less...naughty when transformed, and that is her entire thing.
IFI really needs to step up on the localization, but the actual game is a pretty strong showing with mostly minor (but rather silly and obvious) flaws.
