Dude, I'm gonna be so honest, you've got to just make normal visual novel games and stuff. You've already seen a bunch of people say absolute cinema here, but I really think the visuals and worldbuilding is wonderful as is. I guess it pays the bills, but... Go pure, brother, you could make even more amazing shit!
Also, I'd love to see more focus to individuals in the future as opposed to the general harem stuff :D
