class Base
{
   // your base class methods and data members
};

class Derived : public Base
{
   // your derived class methods and data members
   // derived can use the base class methods and data members.
};

Delete line 6. (template <class game>)

When you get an error, copy and paste the error, please. Just saying "I have an error" is not very helpful.
Error	C2955	'game': use of class template requires template argument list	Project1	c:\programming\my projects\project1\project1\source.cpp	25	
Error (active)	E0441	argument list for class template "game" is missing	Project1	c:\Programming\My Projects\Project1\Project1\Source.cpp	24

If you are required to use class templates:
https://stackoverflow.com/questions/8810224/inheriting-from-a-template-class-in-c
https://stackoverflow.com/questions/10758686/template-class-inheritance

IMO class templates are not a beginner's subject.
