There's actually several because I'm scatterbrained at times.
The obligatory base building is obligatory, and also base building. I think everyone wants this to some degree or another.
I also want bicycles already. This is sorta a personal thing but I do want the ability to travel faster than a brisk jog, that doesn't take such herculean effort to get working like finding a car (and getting it working).
Lastly, and this is a super-personal thing, I want to have milk with my cereal.
In DayZ, there's Crunchin Crisps Cereal, and it eats up your hydration. There's also powdered milk, which also eats up your hydration.
Why can I not mix powdered milk with water to make milk, then mix that with the Cereal to have cereal and milk? I want this to be a thing, for roleplaying purposes if nothing else.
That last one, of course, is incredibly pedantic of me, but I felt the need to mention it.
I am one with my inner moth. Oh hey look a light bulb!
It's only in the darkest nights that you can see the stars shine bright.
