Is there a reason to include Enumerable instead of using game1.player.any?

We include Enumerable and write an each method for the Game class so we can use game1.any? to search through players.

Why not just use game1.players.any?

I think that if you used game1.player.any?{|var| block}, it will just return true if the block ever evaluates to true for any of players in the array.

On the other hand, defining the each method will let you do any action you define. Like the example in the notes:

game1.each do |player|
  puts "Player: #{player.name}, score: #{player.score}"
end

Does that make sense?

couldn't you just use an if statement and avoid all of this?
