In general Nutaku games are imbalanced. For a reason. They want you to spend money. I liked Harem Heroes because it was pretty balanced for a Nutaku game, and enjoyable to engage with. I have no problem with a Nutaku game that goads me into spending $15 every couple months to get that item or girl I want. But most of their games become so unbalanced so quickly that I realize I could just buy the latest PS4 game, for a one time cost of $60, and get a year of gameplay. Harem Heroes was the most balanced Nutaku game I'd encountered so far. If they'd planned it right they probably could have easily convinced me to spend $15 every couple months. Now, I'm worried the imbalances will make me lose interest.
