If you ever saw my room, It wouldn't appear that I am an Anal person, but if you look in the right places, you will find I am, in fact, quite anal about movies and games.
I have my DVD's set up by what kind of box type the movie came in (Does it open like a book, does it have a cardboard sleeve, is it just a black case) and then I sort by boxed sets of Movies and then television shows, and eventually, I'll put movies together based on what they are, if they have sequels.
Same thing goes with games: sort by "Greatest Hits" first, then put sequels with sequels.
I had a nephew come in a few weeks ago and and move one game out of place... I kind of wanted to strangle him and put my game back in its appropriate place.
So I did the latter and avoided strangling Nephews.
