It may seem small, but this new secret for Super Smash Bros. Melee harkens to cool new direction for video games. Games that grow over time - a gamagotchi - without any additional cost or download. If you haven't read the article, here's what's happening: if you have a Metroid Prime and/or Super Mario Sunshine saved game file on your memory card when you boot SSBM, you'll get a hidden Samus and/or Mario trophy for your collection.

Why is this cool? Because this remained a secret for so long, first of all. But mainly because it means that games can have the ability to add features to themselves over time. Super Mario Sunshine is due in August, about seven months after the release of SSBM. Melee is encouraging you to play it well after it's realistic hardcore play period, by providing what are essentially time-based unlockables. Ever wonder about the "TOP SECRET" Motion Detector Bomb trophy? I suspect we'll find out that item's "SECRET" origin once Nintendo releases it.

By the way, 293 total trophies is a pretty stupid number. No doubt more hidden trophies are on the way.

UPDATE (09/02): I've since read that this secret is a complete lie, and now that I have both SSBM and Super Mario Sunshine, I can agree. Rats!
