If The Tyrant was good in your eyes, you should be pleased by most of the available games.
The gameplay is limited to pure grinding with really few indication. Half the events will appear before they make sense in the story. Some actions will block you even if they feel natural in your playthrough. And you can easily circle for in-game weeks without progressing on a story line, just because you never been at the right place at the right moment.
So, yeah, there's tons of lewd, the same small content repeated again and again without real variations, but it's not enough to make a gameplay, nor to make a game well done. But there's hardcore content with a false sense of investment coming from the player. So I guess that some people can find it more appealing than hardcore porn movies.
