DIfference PS3 vs Rebirth?

[Scharfohr]

Is it worth to get while do i have the ps 3 game already (havent started it yet)? i am little bit confused about rebirth. From what i have read this i a remake from the basic game while its still pretty different. (Fighting system from neptunia 3, character appaearing from 3, other Dungeons from what I've seen from videos).

So i am confused now is this a remake now or not? Would i cover the story if i played rebirth instead of the ps3 version or is it better to understand the story, to play the ps3 games and the rebirth games?

Maybe someone can clear that up for me?.

This game on Steam is a port of the PlayStation Vita game, which is a remake/remaster of the first PS3 game.

These are the differences I could find.
Story seems the same although dialogue has been changed.

The combat system is identical to the one found in Victory.
The transportation system works the same as in Victory (and mk2).
In-dungeon abilities are identical to Victory - players can jump and the search sphere is back as well.
Re;birth 1 gets treated as yet another dimension, as characters from other worlds make an appearance.
The Scout System has been removed and the Remake System is in its place. It works the same way as Item Synthesis, except the options aren't limited to item creation. It is possible to find and influence new dungeons through this tool (Harvest Shift is back, so are the Tough enemies), or even change the system like making all the enemies stronger/weaker, making the EXE drive fill faster.
Dialogue has changed much from the original.

the difference is it plays like Victory instead of the first game. In other words you don't just select the target you want to attack from a menue. You have to move within range THEN target them with with the move. Also the Tutorials arent missing key info. The intro is different as well. Honestly I prefer the original game's intro.

The new one is typical upbeat comedy anime intro. It kinda reminds me of the Baka & Test intro.

This game also seems to be missing the transformation cinematics.
