Just finished this yesterday. Well, mostly finished it (A->E endings, and random K ending on the side because, well, Fish!). I'm actually impressed. I had a lot of prejudice going in: anime as fuck, gothic android combat lolitas just because, generally uninteresting combat that is 99% of the gameplay, "OMG MACHINES HAVE DEVELOPED EMOTIONS AND SENTIENCE WHAT A PLOT TWIST!!!" setting... But it's so widely acclaimed, I thought I'd give it a chance.
Turns out, even though each part isn't particularly great, when put together, the game is far more enjoyable than the sum of its parts. It does lovely things with music, camera, gameplay changes, character swaps and quickly becomes pretty engrossing, making you want to see it through.
My only real issue with it in the end is the chip system. It's great in terms of the stuff you have to play with, but it's utterly shitty with only 3 slots shared by your 3 characters, no way to rename them, a godawful UI, and that fusing system grind. Pity because I'd have played a lot more with some stuff had it not been such a chore to reconfigure. At least the auto-configuration helped a bit getting a base setup before tweaking.
