For EVNs, Valentyne Stories: Necromancy.
Beautiful art, cool setting, likable cast but it's been abandoned. The devs did say they might come back to it someday, so...
For JVNs, Kase no Shiro.
I'm a sucker for this type of fantasy Western setting and the art is appealing for its time. Dev's previous game was good too.
Not a game, but translation project: Re;quartz Reido.
It's a case of a great game having the worst luck: at first loc company went MIA. Then it came back and promised to finish the project...only to dissolve soon after. I wish somebody else picked it up for translation...
