I agree with Elliot. When a player lacks the skill, he just uses a walkthrough or cheats or any other kind of help to continue the game. I needed help with some games, cause I lacked the skill while at some points in a game, your character just isn't skilled enough yet to beat a specific goal.
There are very few games out there where it actually comes down to button smashing your way through the game, most of them require at least some skill or strategy to complete.
