Typically we mould our mc as we get to know the other characters, and in doing so we may compromise our intentions for our mc if we take a liking to a certain character or other (e.g. making DIK choices to get with Quinn, or toning the mc down to stay with M&J). This has worked throughout the game until the mc achieved a permanent affinity.
However, when it comes to Zoey, the mc's character is already set in concrete. At this point he's either a DIK or a Chick, and to bring a new character in after this solidification of the mc's personality, certain players may be already locked out of deep involvement in a character that they were not expecting in the first place, but may end up being an integral character in the plot.
Hence the ability to shape Zoey's edges (be they rough or be they smooth). But it's still a gamble. I agree that omnipotently changing a character dulls the relationship. This is in strong contrast to the mc's own influence changing someone, like the enjoyable evolution of Quinn.
So yeah, DPC bringing in what could possibly be an important character (she could just be doing a cameo for one episode for all we know, but they why spend so much time on her introduction) is a bit unorthodox, and being able to shape her as we see fit is also a strange decision, but hopefully it just gives us 4 times the fun!
I kinda agree. I don't know that DPC did himself any favours by going all-in on Zoey's back story. A few people changed their tune about her, but she simply wasn't awesome enough to seriously rock the boat.
She's very human, and has many faults, which a lot of people enjoy about the characters in this game, but as a late starter, she either needed to endure something tragic, or achieve something momentous, to universally entrench endearment among the players; that didn't happen. The closest thing to that was her guitar playing (both tragic and momentous at the same time).
I enjoyed the Interlude, but I only played it seriously once, so compared to the rest of BaDIK, I'd have to say it was a fail. I think it's just too long to say what it needed to say.
I think there are more fans of DnG than you realise.
Personally, I truly hope there will be at least one or two more campaigns before BaDIK is done and dusted. But I get the gripe against it; all the sex scenes are meaningless, they don't progress the mc's relationships in any way at all. But they were still a bit of fun.
