I have a rather strange method for getting rid of my games...
In my closet, I have a brown box with the words, "Box of Shame" written with sharpie on it.
Basically, I take all the games I ever regret buying, or ones that I felt like I spent too much of my hard earned money on to justify, and put them inside the box. They either sit there, rarely get traded in, or I play them on a rainy day when I get bored.
As they always say- out of sight, out of mind. I may have actually spent the money, but with them not around to see, it feels like I didn't, and sometimes I end up liking one or two of them in the end, and enjoying them afterall.
Ahhhh, to be an insane individual.
