I prefer tweets/etc anyway, while I have a bluetooth keyboard it's sort of a pain to message on PSN. Really liking it (made some posts in the
Neptunia Community Thread already). IT's very fast and responsive, combat's very fast especially if you skip animations, only one map has had performance issues so far. Great IQ too. Character models look great other than some low-poly edges on some of the clothes, and while the game has "real" lighting now it occasionally looks a bit odd against the anime characters, but overall it's a solid graphical upgrade and I wouldn't have asked for much more.
They fixed EXE so it's no longer an instant win button, it's more like a resource, and it's no longer retained between fights. Now you spam Rush attacks to build EXE and use it to execute formation skills or EXE skills (not that much stronger than SP skills, but they don't cost SP) or to transform into HDD. Nice magical girl esque transformations for HDD. New combo system is pretty great. Scout system...doesn't suck (that bad), surprisingly. Seems improved in pretty much all ways at least gameplay/graphics-wise. Pretty much all of the new music is good too.
Barely know what's going on story/humor wise of course. Game has a very different structure from the other games including separate story arcs for each nation at one point. Will be cool to see some of the story told without Neptune TBH.
