Poll- Favorite Adult/Hentai Game Types (Patreon)

I will probably doing quite a few poll (in the near future) to get some general opinions regarding games, as I have many project concept ready to go for my next game. It's just a matter of choosing the right one for my resources/budget, development time tables, etc.

As many of you know, Steam's Marketplace allows adult games (as of the last couple of years) which has opened up Western adult content to a much broader audience than ever before. There are all manner of H games available, but generally, the amount of available games from the West (not Asia) is still much lower than Japan. 

Publishers Kupaa Studio and Critical Bliss has ample Steam analytic that have shown us (very clearly) that a wide audience from all over the world is very hungry for unique adult games. Russian and Taiwanese audiences are up and coming for downloading adult content on Steam.
