It's funny how a lot of people associate throwing away boxes and "important materials" as something children would do; I actually used to keep all my boxes and EVERYTHING as a kid and was really compulsive about it, but as I've grown up I realized how useless having a lot of extra stuff is and how it doesn't make me any happier. I admit it that obsessive-compulsive feeling comes back every now and then, but it usually goes away pretty quickly.
I realize many of you are collectors and are into the collectible aspect of these games, but I'm just buying them to play them, really...I used to own hundreds of games and I found that the more I owned, the more I wanted, and it was just eating me up.
I'm not trying to pick on anyone here; if it makes you happy to own that extra box to keep your game in, that's great. For me I just see it as an extra piece that I don't want or need...and when I have something that I don't want or need anymore, then I either throw it away or sell it. I'm trying to become less materialistc with age.
