Of all the romance options I really don't see, no, I don't want to see how it works out with Minsc. Unless we're talking about the next level of friendship commonly referred to as bromance.

I always saw Minsc as a big brother figure, not a romantic interest. And it will remain that way... anyway, Minsc's true love is Boo. Let it end there.

Anyhow, he will most likely be a must have in my goody-two-shoe parties, if Larian does him justice of course and write him properly and true to character.
