Hello.
My interest in visual novels has really been rekindled after reading Steins;Gate on a whim after ~ 1.5 years of ignoring them, and I'm looking to keep that momentum going a bit.
As the title suggests, I'm looking for a VN with darker themes and fleshed out characters who will make me want to emotionally invest myself in them (whether it be positively or negatively). My only other needs are that it be translated to English, playable on a PC (Windows 8, 64 bit) or a PSP/Vita, and preferably lacking in "excessive" (non-storydriven) H content.
A list of the novels which I have already finished can be found here: http://vndb.org/u31245/list. I guess I would classify many of those as having dark themes in some way or another, but my preference would be for something closer to Kara no Shoujo or Saya no Uta, though I would not be averse to a lighter read in a Symphonic Rain type mold.
Thanks for reading and/or sharing any thoughts!
(Hopefully there's enough information here to help.)
