Thanks for both your feedbacks, perhaps I'll release a R18 game from the get go in a future project to test that. Personally , my past R18 game had a dip compared to my non r18 ones so that's why I didn't want to sell an R18 game from the get go. Now it could be the content/plot itself lacking , or the timing (in 2020), but that's just why I choose to add it as an add on as for me personally, my non R18 games seem to sell easier due to reaching more people (streamers and those who shy from r18 games).
And I understand the asking for money bit, but I will say that, the 10K profit goal has always been reached in all my past projects so it's really just a benchmark of standard in interest and me making sure I have enough money to live for the year.
