Ok, Firstly, which version of the game that you prefer, is strictly your opinion, and stating that one version is better than another on a thread like this, is a good way to start an argument.
second, I am confused as to why you would think the version of the game where you hate your brother is better than the one where you love your sister. Granted, their love is a little more than typical brother/sister love, but to cuck your own brother with his wife and then convince her to continue cheating on him with you when he's not around and basically make her, and their daughter, a long distance part of your harem... to me that feels like it would take a lot of hate.
