The best way to select what to take is get a tub and after you go, put the used stuff in it.
I have 2 medium sized tubs for camping supplies. I use them for tent camping with the scouts (boys and girls) for the last 25 years. It has the "I need this stuff".
One is for the Kitchen: Tubs for dishes - 3 (we use a three part cleaning system) Oil, Soap, salt, pepper, spices, cinnamon, sugar, biscuit mix, nested pots, plates, silverware, can opener, Long handled tongs, spatula and spoons for cooking over a fire, gallon plastic bags for mixing and a can of condensed milk.
One for the Fire:Matches, firestarters, hotpads, towels, dutch oven (top doubles as fry pan), small grate, tools - hammer, screwdrivers, pliers, multi tool, scissors, duct tape, heavy needle and thread, first aid kit, hatchet, dish washing scrubbers, hair ties to keep long hair out of the fire and
heavy duty non stick foil-man I love that stuff.
I always take my boxes when I go, even if I am not in charge of the kitchen!
I have my "Marry Poppins" reputation to uphold. It is nice to say..."Oh, Pat might have it!".
Seems like you always forget something....don't fret improvisation is part of camping. Keep an eye out for stuff at thrift stores and garage sales.
At to games for the little ones, Scouts have an emergency game box:

Over the years this has proved to be a real blessing. My box is a
