I think there's a lot that can be explored in the non-VN space.
Games that already blend real-life relationships with fantasy, action, or other engaging gameplay are great places to start, from a developer standpoint, drawing inspiration from. Games like harvest moon, rune factory, and the persona series have great basis in combat and relationships that could easily be extended into a Hgame with more interesting mechanics than the standard VN.
In terms of already-existing HGames, someone mentioned Illusion, who do make great sandbox-style games, but I also look at games like VH and modded skyrim for interesting gameplay elements in a sandbox-style enviroment.
For more action-oriented games, a lot of japanese-only releases get this right. The UnHoly series (before torture) did great platforming, as did games like Iris Action and Lab: Still Alive (1, 2 seemed to fall flat to me)
Eluku does great fighting-style gameplay with Fairy Fighting, and the combat in Wolf's Dungeon isn't bad either, but it's admittedly a lot more niche in terms of sexual content.
Even using a standard VN interface, you can still get a bit more creative. Look at Monster Girl Quest (the first set) for an example there. The gameplay, while simple, was engaging, the visuals varied and often changed based on enemy skill used, and it still kept storyline and character development as a forefront.
Why aren't more VN's like that?
Overall, it takes more work to build these styles of games, and they tend to be shorter and with less content because of it, but there's a lot of potential in my opinion still left to be explored.
