I can say, I am not into dom/sub relationships in games (at least how they mostly are written). However I love how this is written, and don't even consider it dom/sub. While I know the dev has said it is, and others say it is, I am cool thinking what I think. I like that the MC is not playing a power play, he protects his girls, wants to explore with them, mutually, and knows what drives them crazy. He loves them. That is why I play this game. The MC loves his girls, and they love him. If that has dom/sub components, fine.
PS - I cannot wait till 3-3 (or there abouts, if you miss it, I'm cool, lots of renders/content makes up for missing a goal a few days).
