Hey, I am making a Board game framework in C++ (Basically you can create your own TicTacToe, or even chess) It will provide a simple minimax algorithm which will automatically work for any game.  

---
The core issue is number of Pieces on board. (TicTacToe has 2, Chess has 6). But these are essentially just identifiers. I am currently using templates which takes in an enum. 


template <typename Tile>
class Board;


// Implementation of Board
enum class TicTacToeTile {
    Empty, Cross, Dot
};

class TicTacToeBoard : public Board<TicTacToeTile> {
    // Implementation 
};


Is there a better way of doing things? I considered classes but I feel you would need to instantiate classes in the heap and they are essentially only ids which will be too wasteful.
