Ask your patreons first, they matter a whole lot more than joe public here, of which the majority will not pay a cent. I think you should remove your games from free, put some kind of drm in them to prevent people from leaking them. Most pirates are only interested in AAA games not small indie porn games, although some asshats will always leak something.
Most of these games I won't touch until they are fully completed anyway, too many devs decide to abandon their work just when you have got into a story and enjoying it which is really annoying.
All I can say is, you do you, you know what's best for you and what works / sells at the moment. Just remember though, people's tastes can switch in an instant. What once worked might not a third time around. Problem is when using the same characters from previous works is that they get boring really quickly when they appear in something new. What i am saying is that, your going to have to really come up with something completely different from what you have already done.
