in terms of save / load format I approach it (and will likely continue approaching it this way as its efficient and simple)

• Header data
  for each object type
  • Identifier for object (anythings fine so long as you can tell what it is while loading)
    for each instance of object
    • a true bool
      object data
      
    a false bool (to tell the load loop to stop loading this type of object)
    
  Footer data
  

its about as easy, flexible and compact as you can get pre-compression, a testament to "Simplicity is Supremacy"
and you could apply this to just about any engine.

EDIT: I'd like to apologize for the almost back-seat deving, these are just things I've forgot early in projects and payed the price for later, I figured I could save you the trouble before it hits you.
