Thanks for the help it worked straight away. Didn't see where I went 
wrong. I was using parentheses instead of the brace to access the array.

So in turn when entering an array index number on the
selectGame = games[gets.chomp.to_i] it returns the string value
of the indexed number entered by the user

And where I have

# puts "You chose #{selectGame.gets.chomp}" it already has stored the 
user input so I don't need the gets.chomp method there.

Thanks for the help all.
