...but it would help you further to stand out of the many other games.
You wouldn't be the only one, because some other games did it too already, but there arent a lot at the moment.
im not sure if that "standing out of the others" really is the worth of its price in this case.
for part-time and small devs (probably more than 95% of all devs) adding va is a pure luxury.
even more as it could be really tricky, as you have mentioned.
besides, unless names/relations arent fixed (and that is rarely done nowadays, and 99% of players hate that) that hardly can be done properly...otherwise it would be silly to hear terms as "player" "female friend" "gf" or some pronouns, complete avoidance or so, instead of intended names and lines.
ss, i dont see it, at the current developing state, as a thing that can improve any game at all, apart from that "standing out of others" part.
