Guess I'll have to wait a little longer before I decide whether to buy the game or not, depending on how they handle the marriage and kid thing.
As for those of you who can't understand why a set character sixuality matters to some of us, this is why:
Almost every game, book, movie, song etcetera out there is about a straight character. It's not a question of whether or not the player character is straight in this game specifically, it's more like "oh no, not AGAIN!!!"
Imagine if the opposite was true. I think a lot of people (myself included) would have a huge problem with almost every game, book, movie, song etc. featuring a gay character. And if a game series that were known for allowing freedom in that regard suddenly featured Gay Main Character no. 264852799136567187658769837516235876, all of those people (myself included) would be rightfully upset.
And that aside, there's also the baby. One might be straight and not want a baby. That's in fact pretty common. And that aside, there's also the fact that your character has a preset husband or wife. Not every straight person is attracted to the same type of appearances.
There's simply too much restrictions on core parts of the player character's personality. Making it less our own character, and more someone else's.
