Preserving tradition has become a nice hobby
I used to pride myself on my video game collection. My collection of GameCube titles, in particular, was a sight to behold. The GameCube came out just before I graduated high school, so while I was in college and working part-time I had quite the expendable income with which to buy whatever I wanted. So while I picked up every GameCube game worth playing, I also picked up a few terrible games just because they were part of a series and would look nice on my shelf.
