Unfortunately SAO. But other than SAO, it was either re;zero or so I'm a spider so what. Unless you count yu yu hakusho, but until last year I had only watched the first arc.
The last thing I reread was goodbye eri by tatsuki fujimoto. it has good reread value, but I'm not sure I liked it better than the first time. Other than that, I don't reread much since I've got a lot I still want to read for the first time.
It's a different medium, but manga artists' artstyles tend to change over the course of a long series. 99.9% of the time it's not a bad thing. As long as it isn't a sudden jump to a new style, a lot of readers probably wouldn't notice unless they go back and re-read older chapters.
If you're open to anime, Serial Experiments Lain. I don't know if it's actually supposed to be a horror anime, but I definitely felt unsettled the entire time I watched it.
Launcher works, installs the game fine, but the game itself doesn't launch.
Wasn't really hoping to play it anyways, I have too many other games I still need to finish (like my second playthrough of nier:automata).
Working on that exact thing right now, actually. And, I don't know whether or not it's normal, but I've seen it used to great effect, so if it has a big impact on the rest of the story I think that it'll be a good thing.
