The title says it all - how do you transport games from one locale to another? I don't mean your whole collection or a large part thereof - I mean when you carry games over to a friend's house or to a party, or if you loan a game or two to a friend or coworker.
Do you use the games' own boxes? A disc spindle like what is sold with CD-R's? Paper sleeves? Generic CD jewel cases? DVD cases? Thin cases? Perhaps disc wallets which hold several discs in internal sleeves? A bag or knapsack of game cartridges? Carts only? Or do you figure for disc-based games they are loaner copies and only share your extra ones with a bit of damage so you don't worry about it?
