Most games, when purchased new, come with the standard stuff: a box or case, a manual, maybe a little advertisement for a related game or product. Do you keep any of that stuff, or toss it and just keep the game disc (or cart or whatever media is used)?
I always try to keep all of it now, but I didn't do that so much back in the day. Nintendo always used to box stuff with little flyers of Nintendo Power advertisements and those warning booklets that were the same in nearly every game. I either tossed those back in the box or tossed them entirely. Back in the Atari 2600 days, I think I only kept one game box, which I put all the manuals in. Everything else got tossed in the trash.
