Great! For Zombie Apocalypse, you should check out the
character sheets and choose unclaimed characters you would like to play. You can post your selections in the
character selection and discussion thread, and you can ask questions there. I recommend choosing characters that were added in Chapter 2, as there's very little catching up for them. You should only read In Character (IC) threads that contain one or more of your characters, and only those parts of the threads where they are present.
This thread contains a list of characters and the hyperlinks to each thread in which they appear. Unlike in most games, in this game you are allowed to play multiple characters. I recommend choosing three, as this game is highly lethal, but you may choose any number up to four. Once you've made your selections, I'll send you your characters' secrets in a PM. Once you've read those and caught up, you are free to start posting in your characters' IC threads. The game has been stalled for some time, but I plan to get it moving again in the next few weeks.
There's more catching up to do in The Masque of Nyarlathotep, and there you'd probably need to create your own character from 1517, unless you want to take over an abandoned character.
This thread has occupational skill lists and starting money for a selection of occupations, though you're free to choose an unlisted one, in which case I'll provide a list for you. The
Character Creation/Rules thread tells you how to do it, and you would create a character in that thread.
