The only Neptunia game that I've played is the 1st one on the PS3 and, yeah - it was pretty rough around the edges.
What I remember as my 2 biggest annoyances with it were:
1). being unable to re-sell anything at the store (overly cluttered inventories full of old, useless, outdated, & obsolete shit just...vex me + the extra $ that you can't get for it early in the game like you can in (what? almost every RPG made in the last few *decades*) is another annoyance
), and
2). the stupid-ass healing system
I mean, can you simply use and/or consume one of your healing items either in or outside of battles (*again*, like you can in most RPG's made in the last few *decades*?
Answer = Hellz NO you can't!
Instead, wouldn't our fan-base just adore & enjoy it if we take a simple turn-based RPG staple (like the healing system) and turn it into a system almost identical to FF XII's 'gambit' system (which, don't get me wrong - worked in & suited FF XII just fine); so, something simple & intuitive (like using a freakin' potion) becomes variable-based (ie "if HP = < 30% then chance to use a healing item = 20%", etc...
...blech
/rant
I wouldn't say that the entire game sucked (personally, I'd rate it at around a 6.5/10 (which, if you use ALL TEN #'s of the 10-point scale like I do -and- very few reviewers seem to; that's a different rant for another day, though) does not necessarily a bad game make...
Anyways, what kind of game is this "Tears to Tiaras" & what's its premise/what's it like & about?
