You can figure out which has a translation and which doesn't, which is about 70%.
i'm currently looking for a good hentai RPG like rance or utawarerumono, but spesifically i'm looking for 1 with english translation
Shin Koihime Musou & Moe Moe taisensou(because like SRW)
~Sniping All the Target~~The Shooting Sniper Gundam Zabanya~
I don't know moe moe taisensou, but I can assure that Shin Koihime Musou isn't rpg, it just has some crappy boring battles that could be called a rpg-element, but it's too far from being rpg anyway.
btw have any of you played Casual Romance Club??
i'm also looking for a game like that..
