The main reasoning behind this is simple: people tastes vary. So, instead of making a game with GxB and GxG romances and ask $20, I would split it in two (like I did for Spirited Heart) and then let the user decide what they want to play and pay. It would be easier for me (and probably more remunerative) to just have a single "base version" of Nicole with 3 GxB and 1 GxG, and then do an expansion with extra mixed stuff. But the reality is that many people who play otome absolutely don't like GxG, and vice versa! (and I guess the same for BxG and BxB).
So if I just include the 3 boys, I could price the game less (for example $15 instead of $20), and then do a proper yuri version with two more GxG for same amount. People who buy both would get a discount of course, so the final price would be only slightly more the usual price of my dating sim games and anyway proportionate to the amount of content.
For RPGs, that is different, since in those games the main purpose is not just the romance, like the dating sims/VNs. There are the battles, items, big decisions, skills, the story, etc etc so makes sense to just include everything and offer all kind of romances like I did with Loren or Planet Stronghold.
That's what I personally think should be the right way to do it, but I welcome any suggestions. If people are fine paying slightly more (like $25 for Loren/PS) to have "everything" at once, would be fine by me of course
