In a way I'm a bit torn, because while I lean heavily on the fixed romance side of things, I can't help but remember games where the fixed romance makes the game . . . unpleasant, to put it lightly (and, unfortunately, only one of these gave me an 'evil' brother in the first ten minutes that was willing to off one of the characters for me).

This isn't often a problem with 'pick your match' systems, but, at the same time, I find those often come off oddly, where things feel contrived and unnatural or I feel that characters suffer to accommodate my possible choice, like they have an open door towards my character that doesn't seem to fit. Sometimes it works, but when it does I often feel like I just took the choice the devs wanted me to, and when that happens it might as well just fall under the set romance option. Both can work out, but I generally find I prefer set romances.
