If you are still looking for people I would love to join this game. You said more the merrier, so hopefully that stands!
I've little experience with Deadlands Classic, but I've GM'd multiple Reloaded games for my table-top group (including The Flood and Last Sons), which makes me very familiar with the world. I'll post no spoilers though, don't worry, I abhor them! It's more fun to watch the reactions of those new to the setting as they learn the various truths from "behind the screen" than to ruin it.
Looking through character creation, I did not see Texas Ranger or Agent available, not sure if that is a Classic thing, a choice you've made, or just haven't made it into the Law Man edge text. If you are allowing them, I'd love to play a "one riot, one ranger" Texas Ranger. :) Otherwise, I'm leaning towards a Doubting Thomas gunfighter/gambler, looking to earn the title of fastest draw in the west!
