It really has nothing to do with how good or bad the plot is. I just don't like LIs or characters I like dying, so I don't play games where that happens: I play for an enjoyable experience, and that's certainly not what it is. So, either it turns out that when the game ends that LI will be able to survive to be part of the MC's harem, or I will still not be able to overcome that part of the game (I don't consider the idea of playing with another guy other than the MC as a real option, if the game forces me, so my goal is that this guy doesn't have any relationship with anyone, nor sex scenes, of course).
Furthermore, it should be a game with a romantic route with each LI (being able to avoid prostitution, rape and possibly slavery), where we could avoid using mind control to have sex with the LIs (and also, unless if it's something really soft, in the romance part with them)
