As I've said, I'm an organization nut when it comes to my video games. Beyond keeping track of the games in a database, I also keep them stored safely in cases. Games for the Nintendo GameCube, Wii, and Sony PlayStation 2 are easy enough to store (they're just DVD cases, after all), but when it comes to Game Boy Advance games, I make use of the extra storage slot inside a Nintendo DS game case. For those who are unaware, DS cases include a special slot inside to store a GBA game in addition to a DS game. Being the neatnik that I am about these things, I don't just shove GBA games into whichever DS case has a free space. Oh no. I have a system, a way of correlating GBA games to DS counterparts so that when I want to play a specific GBA game I don't have to go hunting through a stack of plastic to find it. Allow me to share my sorting method with you. It could come in handy someday.
Some match-ups are obvious. Super Mario Advance 2: Super Mario World
goes into the case for New Super Mario Bros. since both are 2D
side-scrolling Super Mario games. Sequels go with the original game,
so it makes perfect sense to keep Super Mario Advance 3: Yoshi's Island
in with Yoshi's Island DS. Then things get a little more loose. I
keep Mario Tennis: Power Tour with Mario Hoops 3-on-3 since they're both
Super Mario sports games. Sonic Rush and Mega Man & Bass stay
together since they're both third-party platformers starring
long-lived mascots. Finally, things get more abstract as I look for
basic commonalities shared between two games. Do you see why Super
Princess Peach and Drill Dozer go together? It's because they both
have a woman as the main character. I keep Star Fox Command and the DS Rumble Pak together because the original Nintendo 64 Rumble Pak came packaged with Starfox 64 back in the day. It's not a perfect system, but it's as darn close to one as I could come up with, and I never have to search the cases to find that one GBA game tucked away somewhere. I now entrust this knowledge to you. Store it somewhere safe.
