Just played Maid Mansion and I have to say it was quite an enjoyable experience. However one thing that irked me was Pa Zong's ending required a ridiculously specific route to achieve (I really wished there were more routes for her). That and I felt that my actions had no consequence on the story until the very end as most just result in maybe a single line change.

For example when deciding what to do with Takako my choice seems to have no real effect on the chain of events until the end where either Narumi gets stabbed or I end up marrying Takako.

This also reflects itself in the way the MC acts as once I choose to basically punish everyone and yet my character still acts the same way as when he is "kind". I would like to see more character in the MC maybe by hiding options from the player (such as with the massage) to flesh out the MC. I was also hoping that all the characters would get the same amount of attention but it really felt I was just pushed towards two (maybe three) of them. I was fine with the no harem ending though however it didn't feel satisfying at times as I was trying to find the other endings and just getting the same scenes over and over. Over all though the game was very enjoyable and my only real complaint was how some characters seem to less attention on them than others.
PS really looking forward to sinful sisters the sisters look great!
