The writing of the code went well. I am just not sure how much commenting is necessary. I walked through most of my code with comments. Is this excessive?
Actually, if you wanted to make it really terse, you could also have combined it with the "gets" piece, like so:
  puts "Would you like to play again? (yes or no)"
  if (gets.chomp.downcase == "yes")
    game
  end
