To me this basically reads: we don't want people to plan their characters out before they play the game. Isn't that the point here? Designing a role and playing it? Even if that "role" is just the player interjected into the story, I already *know* what I do and don't find attractive before I start to play the game. As soon as I see the companions lined up and have two lines of information about them, I'm already going to be measuring one against another based either on myself or my characters preferences.
Lets not get into definitions of what it means to "design a role" or what it means to roleplay or what have you. I design a role when I play RPGs as well, to which I then react accordingly to the events that I am given while in the game. This is different than yours (which is fine), but I'm definitely the type of gamer that is fluid and organic in my relationships.
But I'm also the type of gamer thats like going in with the idea and concept, and I organically mold it to the game as I play through. Ideally I don't even know who the characters are. Sometimes my characters have in game epiphanies and revelations and they end up being completely different and it wasn't planned at all (My KOTOR playthrough fit this to a tee, and it's one of my favourite memories in gaming).
I'm not saying that you wanting to do it your way is lesser than mine, but it's just that I don't feel that something like this means we aren't letting players plan their characters, unless we only take a specific subset of "planning."
The principal reason why I can't plan through a full playthrough with my first character, though, is because I feel that the game will innately force me to deviate from what I want to do in it because I'm unaware of the game mechanics and narrative elements that may or may not substantiate the goals of my playthrough. But I'm also someone that (if it were up to me) wouldn't reveal who the romances were (whether or not this makes me a jerk or not, I suppose, is up to the other person) and I'm also someone who is okay if a game doesn't have romance content. It's just different.
