Snapshot

Snapshots became a reality in Super Smash Brothers Melee, however they were poorly implemented. To take snapshots back then, one would have to enter "camera" mode then take pictures of the character(s) using an additional controller (1 controller acts as the camera). This was a near pointless option, as it would save to a GameCube memory card, which didn't exactly grant you the option of doing anything with the snapshot.

Brawl however reinvents the snapshot idea, and implements it in a much more useful fashion. This time, no matter what mode you are in, you can pause then take a snapshot. How great is that? It makes sense to, because funny instances or scenarios arise at random, as such, you can snapshot them as they come. Where as before, in Melee, you'd have to "recreate" these scenarios in camera mode... just pointless.
