I get attached, but that's just how I have fun with my games. I'm not so overly attached that I'd throw myself into a raging river if Rosie packed up and left tomorrow, but well...
I am a storyteller. I'm a writer. I am the kind of person who loves adding backstories to blank slates, who loves personifying those things which have no soul. I could make you form an emotional attachment to an iron if I wanted to, but I'll spare you the burn (get it? haw). My point is that a lot of my fulfillment and enjoyment comes from forming those attachments because it has become a huge creative outlet.
You're looking at someone who spends more time in the Sims 3 CAS than the actual game. I developed over 50 families and I'm -still- making them. 2-3 generations of each family planned.
Animal Crossing is written so well and yet so vaguely. It's the perfect story fodder and I love making up small stories for all of my cute little villagers. While I definitely know it's just a game and they're just mindless little programmed pixels, the fact remains that somebody out there had to come up with all of that dialogue, with their designs, with their loves and hates and everything. People spent so much time creating each and every one of those characters. Even the characters you don't like are someone's baby.
Not to bring religion into this, but think of it as all of us, being made in a unique image. Lovingly created. I'm not religious by any means, but I can respect the idea that everyone is made special~
So that's how I think of the animals. They were someone's loving craft, someone beautiful idea. They created villagers who, even if they seem ugly, still have fans. And while they act like stereotypes sometimes, or just kind of ditzy, we also need to bear in mind that with a game already so vast and populated, they've really done a beautiful job so far and it can only get better~ Perhaps someday, ever animal can have more uniqueness to them, but for now, I am ok with what we have, and I am ok doing a little work on my own to flesh them out a bit~ It adds to the fun.
...So pardon the essay, but to answer your question, yes, and I always will~
