I'm running a Deadlands campaign with players who come entirely from D&D and have never played Savage Worlds before. All five people in the group have made nearly identical characters (gunslingers) with practically the same stats, hindrances, and edges. I've tried to get some of them to branch out, but everyone is dead set on being a gunslinger.
This is going to make things sort of hard to deal with, because the group is very one-dimensional. Should I try to change the adventure around this so they can deal with it? Or should I just let them have a hard time until someone dies and decides to mix it up? Should I be extra mean and throw something at them I know they can't handle?
