Great questions. I am in the very same boat as my son in-law wants to have me DM a game for him, his sister and my Grand Kids (4). Sister wants to play a Medical type i.e. A surgeon or such from a mash. Son in-law would like to be a special ops Officer. The Kids just want to play with grandpa’s miniatures and on the big game table (4’ by 8” sand table)
Hmmmm! Soooo why is that group together near the rally point of Kalisz and how much equipment to have them try to use and keep track of. Me, I am retired and have all the time in the world to make lists and various problems for them to solve. The thing is they have no military experience other than their father being in the Army and a CIA analyst and cop. Well that may count for my daughter marring into their clan.
So we will let them start with pretty much whatever they want (notice the royal we, in DM mode already)
They will be here in an hour or so, I will let you know what the plan is then and you can have a laugh.
