I am exactly the same way when it comes to video games. The worst thing about getting 75% of the way through a game and then putting it down for a while is that when you do finally return to said game you are no longer good at it and have to re-learn all the controls. When you combine this with the fact that you probably stopped playing at a point where things were getting really difficult in the game this is a bad combination because seasoned veteran player you is certainly better than what button makes me jump? you.
