 The Subclass Sandbox pattern is a very simple, common pattern lurking in lots of codebases, even outside of games. If you have a non-virtual protected method laying around, you’re probably already using something like this. Subclass Sandbox is a good fit when:
 
 -   You have a base class with a number of derived classes.
-    
 -   The base class is able to provide all of the operations that a derived class may need to perform.
-    
 -   There is behavioral overlap in the subclasses and you want to make it easier to share code between them.
-    
 -   You want to minimize coupling between those derived classes and the rest of the program.
