Don't know how you feel about real porn or HTML, but Just One More Chance has a pretty good gameplay loop. It starts a little grindy at first, but as you progress and get achievements and unlock new scenes and interactions you pretty rapidly pick up more and more skills and options.
Long Live the Princess is admittedly a VN, but it has gameplay elements based around using clues to resolve small mysteries around the plot and the girls in order to progress your relationships with them.
Masters of Raana has you building your wealth and powerbase as a local patrician, and in the process gaining access to the women in the game (who you can treat as lovers or broken sex slaves, your choice).
Of Devotion and Despondence handles the main girls more like a VN, but the rest is built around a combination of RPG, sandbox/exploration, and base/party management.
