I heard a lot of good things about Okujou no Yurirei-san. It's very popular in Japan. Even got two volumes of spin-off manga (run in Hirari, by Itou Hachi) and drama cd.
About the upcoming steam release. I saw the CGI and yep, the sex is soft, but it's there, it's on screen and you can hear all moanings and dialogues. I'm happy we will get uncut version on steam. Anyway, this and SonoHana is a must buy for me.
