Adds an option for each arcade game to turn this option off or on. I haven't seen anything yet in the game saying it prevents getting achievements so that's a plus for people that like that.
In some (or all?) of the special challenges you can take part in, it can't be used like certain other helping features in some of those, which I haven't yet checked out this part of Stadium yet.
For a buck, just get it. Some of these games are tough even when you set it to easy so it could be something you want to turn on for at least certain parts of a game that's ridiculous or flat out unfair.
