Hello there!

I would say basing roles off of yourself is something I really don't like or if you do, I'd probably rather not know. (ex: some RPers name characters after their username, which seems a bit weird to me too) I would say a mourning phase depends on the characters but they may not have the time to pause and think about loved ones since as soon as they exchange names and some people give a backstory (not everyone will get to all at once, that would take too long so probably most or half will have to do it along the way), the plot will kikc up and require some moving and interaction with the new world and its contents. Since it is getting a bit crowded, I will need to say acceptance will depend on your character compared to the others approved since diversity will help us more than say people with the same COD or personality or age range.

If you will like to edit your above post to show what direction you may be going in, let me know though.
