It would be even better if anybody could end up with anybody else depending on your choices, like in SO2.
Oh sure, but I don't really know a single game that does multiple/player-choice romances well. They always feel a bit too disconnected from the main story. Obviously.
There are games where I'd love to have a choice over the romances though. Xenoblade comes to mind immediately. Fiora is so annoying and Melia is so much better in every way, but Shulk is too goddamn blind to see it. Stupid cunt.
