It's funny since I've just started getting into the Psychological dark stuff - most dark psychological games or whatnot.
I've just read Doubt and Judge (stories unrelated, but it's a series of different death games). Judge is a lot better than Doubt, but translators dropped it for some reason. Someone did write about what was not translated which was good enough for me. I think appreciated Judge more because I read Doubt though which I'd rate around a 6 or 7/10, but it was still quite enjoyable (despite having a few predictable parts). I have heard Liar Game is brilliant though, but I'm planning on watching the drama first before reading the manga. I've heard nothing but good about it.
Sshounen stuff, a lot of the stuff I've read have been turned into anime like Assassination classroom, Shaman King etc. I'm hating myself atm for not keeping track of my manga, there's some good ones I've read but I can't remember them >__<
How'd you find Apocalypse no Toride? I've heard about it and wanted to read it.
