Gamified game development! My favorite ones:
Equal Opportunist (10 points)
Write a class with public, private, protected and internal members. It’s all about scope.
Interrupting Cow (5 points)
Have 10 breakpoints in a file. Where’s that bug? Could here, could be there, could be anywhere.
UML God (5 points)
Create a UML Class Diagram 10 times. Code is for sissies. Models! Models! Models!
