Haha to true.surprising how many people put it like that or any name ending with s for that matter
Got taught as it already has a "s" on the end it only needs a ' where as if it doesn't have a "s" it needs a 's on the end.
"James" is my/your name, "James' " is when speaking to/about more than one "James"
Like Game, means one Game while Game's means more than one Game.
It happens though, i just like correcting Luke about it
