This is probably going to be something I am going to regret, but...
My idea is to keep a list of the gaming stuff I purchase over the year to see how much I spend and what I spend it on. I started doing this last year and the idea petered out before the end of January. So I 'intend' to keep the list of purchases and their cost over on the right side. It might be a good cure for those impulse purchases. Two of which I just made.
Here goes.
