Harem Hotel and Mythic Manor.

Harem Hotel has roughly 10 hours of content and Mythic Manor is close to it.

Unless you go for Japanese VN's, some of those reach upwards of 50 hours if you do all routes.

Personally I like RPGM's like Roundscape Adorevia, Last Sovereign, Renryu Ascension and Legend of Queen Opala. My last playthrough of LS was 75 hours.

I prefer story centric games but all of those have quite a lot of H content too.
