As I work through some character ideas, I was curious if you had a specific age range that you wanted us to shoot for? Would it be ok to go with a more mature character (maybe 50s or 60s)? He wouldn't be as physically adept as some of his younger counterparts, but I could still see him contributing to the group, perhaps as the negotiator or the chauffeur.
That would be perfectly fine! I didn't have any age in mind. In fact, if the characters were more varied and different from one another, that might add intrigue to the story.
