Honestly, I would love that. But there is the issue, could we switch characters? I would hate to be stuck as 'Mate Center' or as a 'Recruiter' for my whole life! I would slowly cry if I got stuck as my 'joke' characters such as SPARKLEGURLBLUE, even though she is deleted, still. I would also think many of the younger people would cry and immediately dump their current mate or some would even attempt to dominate everyone by saying they were given special powers and try to be King/Queen. While those who have made many online friends would hug each other for perhaps the first time, and shed tears of actually being able to have a somewhat face-to-face conversation and hunt together and eat. Not to mention those who have a true online relationship and didn't just matebeg or found at Mate Center would perhaps share their first kiss.
Personally, I would be overjoyed that I am no longer connected in the real world, by terrified about dying since I have no idea about hunting, or acting as a canine or a feline. Feel we would all have trouble, so if we had the choice of switching characters, I would maybe stay on a character that is in a group, so we could all hunt together to survive. If not, I would attempt to go to Bonfire or FP to find a group who would perhaps like to work together for a while, while everyone learns how to hunt. In order to get one rabbit, ten people would have to help, and then eventually be able to hunt alone.
I feel all the world of FeralHeart would also be too small for everyone. People who claim territory, and threaten to kill if you don't leave, some would probably make real packs. Many would perish during this.
Though I also would question if the block button works, that would be very useful, if you were in a life and death situation, block the person so you don't get injured!
And to Sammi, oh dear god I would be terrified to see what a canine/feline version of me would look like! Many would probably scream they dislike their character and want a do-over.
Though this is a very interesting topic to think about!
