Where

Find the Game method, and look for:

string nextPlayer = "a";

Idea

create a random, then generate a random number, and then use it to decide if A or B goes first.

So we need to just declare nextPlayer instead, and also add the following code:

string nextPlayer;
Random rnd = new Random();
if (rnd.Next(100) <= 50)
   nextPlayer = "a";
else
   nextPlayer = "b";
Console.WriteLine(nextPlayer + " goes first!!");

This generates a random number between 0 and 100, we therefore check if the random is less than or equal to 50. The position of the if statement could change depending on where you would want it to go, at the moment it decides who's turn before asking if you want to load a saved game.
