I finished playing Ever 17 (PC version) a few weeks ago, it was definitely a great story!
I considered getting Never7 or Remember11, but in the end I gave that up since I read that Never7 is more of a "dating sim" compared to Ever17, and Remember11 didn't have a "proper ending". I think I read that they fixed that in the PSP remake by adding a few more endings, but it hasn't been translated... Too bad!
While looking around for other officially released English VNs for PSP, I found out that they're actually working on an English version of Corpse Party: Book of Shadows for PSP, so I guess I might get that one once it's out. I liked the first Corpse Party game. Very freaky playing with a headset.
The sequel is AFAIK pure VN, without the 16-bit walking around part.
Oh BTW I made a version of Der Mond, Das Meer with both Sara and Coco by merging together both of their versions that I found on Youtube:
