Hi Robin,

I know two good reason why you should use formating functions over 
string concatenation via the plus sign:

1.) formated strings are better translatable. e.g.
"The string '%s' is more then %s characters long"
is easier to translate then the three strings:
"The string '"
"' is more then "
" characters long"

2.) Whitespace mistakes are easier to see. e.g.
(i + "coins") and ("%scoins", i)

Sure you can make the mistake to provide not enough arguments, but 
that's not so worse:
a.) Some IDEs, like Intellij IDEA warn you if you call a formating 
function with to few arguments.
b.) A exception will be thrown at the time the function is called, if 
there are not enough arguments. Thus you will notice your mistake very soon.

Best regards,
Florian
